Distance and Displacement

Distance: total path length travelled (scalar).
Displacement: change in position from start to finish (vector).

Speed and Velocity

Speed: rate of change of distance. $s = \dfrac{d}{t}$
Velocity: rate of change of displacement. $\vec{v} = \dfrac{\Delta \vec{s}}{\Delta t}$

Acceleration

Acceleration: rate of change of velocity. $\vec{a} = \dfrac{\Delta \vec{v}}{\Delta t}$

Average acceleration:

\bar\{a\} = \frac\{v - u\}\{t\}

Instantaneous acceleration is the derivative of velocity with respect to time.

Where:

$s$ = displacement

A ball is thrown vertically upward at $15\mathrm{ m/s}$ . Find the maximum height reached and the Time to reach it.

At maximum height, $v = 0$ .

V^2 = u^2 + 2as \implies 0 = 225 + 2(-9.81)s \implies s = \frac\{225\}\{19.62\} \approx 11.47\mathrm\{ m\}

V = u + at \implies 0 = 15 - 9.81t \implies t = \frac\{15\}\{9.81\} \approx 1.53\mathrm\{ s\}

Finding Displacement

The displacement is the area under the velocity-time graph. For areas below the time axis, the Contribution is negative.

A car travels at $20\mathrm{ m/s}$ for $5\mathrm{ s}$ Then decelerates uniformly to rest in $4\mathrm{ s}$ .

Total displacement:

Rectangle: $20 \times 5 = 100\mathrm{ m}$ .

Triangle: $\dfrac{1}{2} \times 20 \times 4 = 40\mathrm{ m}$ .

Total $= 140\mathrm{ m}$ .

Total distance $= 140\mathrm{ m}$ (no reversal).

Average velocity $= \dfrac{140}{9} \approx 15.6\mathrm{ m/s}$ .

Free Fall

Gravitational Acceleration

Near the Earth’s surface, all objects in free fall accelerate at approximately:

G \approx 9.81\mathrm\{ m/s\}^2

This value varies slightly with location and altitude.

Key Results for Free Fall

Objects dropped from rest: $u = 0$ , $a = g$ .
Time to fall height $h$ : $h = \dfrac{1}{2}gt^2 \implies t = \sqrt{\dfrac{2h}{g}}$ .
Speed after falling height $h$ : $v = \sqrt{2gh}$ .
In the absence of air resistance, all objects fall at the same rate regardless of mass.

Measuring $g$

Method 1, Free fall: Drop an object from a known height and time the fall.

G = \frac\{2h\}\{t^2\}

Method 2, Pendulum: Use a simple pendulum of length $L$ and period $T$ .

T = 2\pi\sqrt\{\frac\{L\}\{g\}\} \implies g = \frac\{4\pi^2 L\}\{T^2\}

An object is dropped from a height of $45\mathrm{ m}$ . Find the speed just before it hits the Ground.

V^2 = u^2 + 2as = 0 + 2(9.81)(45) = 882.9

V = \sqrt\{882.9\} \approx 29.7\mathrm\{ m/s\}

Projectile Motion

Principles

Projectile motion is the motion of an object launched into the air, subject only to gravity (ignoring air resistance).

The horizontal component of velocity is constant (no horizontal acceleration).
The vertical component of motion is free fall (constant acceleration $g$ downward).

Resolving Velocity

For a projectile launched at speed $u$ at angle $\theta$ to the horizontal:

U_x = u\cos\theta, \quad u_y = u\sin\theta

Equations of Motion

Horizontal (constant velocity):

X = u\cos\theta \cdot t

V_x = u\cos\theta \quad (\mathrm\{constant\})

Vertical (uniform acceleration):

Y = u\sin\theta \cdot t - \frac\{1\}\{2\}gt^2

V_y = u\sin\theta - gt

V_y^2 = (u\sin\theta)^2 - 2gy

Time of Flight

At landing, $y = 0$ (assuming same level):

0 = u\sin\theta \cdot t - \frac\{1\}\{2\}gt^2

T = \frac\{2u\sin\theta\}\{g\}

Maximum Height

At maximum height, $v_y = 0$ :

H = \frac\{(u\sin\theta)^2\}\{2g\}

Range

R = u\cos\theta \cdot t = u\cos\theta \cdot \frac\{2u\sin\theta\}\{g\} = \frac\{u^2 \sin 2\theta\}\{g\}

{/* prettier-ignore */}

Adjust slider a (launch angle $\theta$ , try 0 to 1.57 rad) and v (initial speed, try 5 to 20) to explore how angle and speed affect the parabolic trajectory. Notice that $\theta = 45°$ gives maximum range.

Maximum Range

The range is maximised when $\sin 2\theta = 1$ I.e., $\theta = 45\degree$ :

R_\{\max\} = \frac\{u^2\}\{g\}

Complementary Angles

For complementary angles $\theta$ and $(90\degree - \theta)$ The range is the same (but the Trajectories differ in height).

A ball is thrown at $20\mathrm{ m/s}$ at $30\degree$ above the horizontal from ground level.

Time of flight:

T = \frac\{2(20)\sin 30\degree\}\{9.81\} = \frac\{2(20)(0.5)\}\{9.81\} = \frac\{20\}\{9.81\} \approx 2.04\mathrm\{ s\}

Maximum height:

H = \frac\{(20\sin 30\degree)^2\}\{2(9.81)\} = \frac\{100\}\{19.62\} \approx 5.10\mathrm\{ m\}

Range:

R = \frac\{(20)^2 \sin 60\degree\}\{9.81\} = \frac\{400 \times 0.866\}\{9.81\} \approx 35.3\mathrm\{ m\}

Speed at maximum height:

At maximum height, $v_y = 0$ So speed $= v_x = 20\cos 30\degree \approx 17.3\mathrm{ m/s}$ .

Trajectory Equation

Eliminating $t$ from the horizontal and vertical equations:

Y = x\tan\theta - \frac\{gx^2\}\{2u^2\cos^2\theta\}

This is a parabola, confirming that the trajectory of a projectile (without air resistance) is Parabolic.

Air Resistance (Qualitative)

Effects of Air Resistance

Air resistance (drag) is a force that opposes the motion of an object through air.
Drag force depends on: speed, cross-sectional area, shape, and air density.
At low speeds, drag is approximately proportional to velocity: $F_d \propto v$ .
At higher speeds (turbulent flow), drag is approximately proportional to $v^2$ .

Effect on Free Fall

Without air resistance, all objects fall at the same rate. With air resistance:

Objects reach a terminal velocity when drag equals weight.
$F_d = mg$ at terminal velocity.
Heavier objects (with same shape and size) have a higher terminal velocity.
A skydiver reaches terminal velocity of about $55\mathrm{ m/s}$ (belly-down) or $90\mathrm{ m/s}$ (head-down).

Effect on Projectiles

Air resistance:

Reduces the range.
Reduces the maximum height.
Makes the descent steeper than the ascent.
Changes the trajectory from parabolic to asymmetric.

In IB Physics, unless stated otherwise, ignore air resistance in calculations. When asked to Describe the effect qualitatively, remember that air resistance always opposes motion and reduces the range and maximum height of projectiles.

IB Exam-Style Questions

Question 1 (Paper 1 style)

A car starts from rest and accelerates uniformly at $3\mathrm{ m/s}^2$ for $8\mathrm{ s}$ . It then Travels at constant velocity for $12\mathrm{ s}$ and finally decelerates uniformly to rest in $4\mathrm{ s}$ .

(a) Find the total distance travelled.

Phase 1: $s_1 = \dfrac{1}{2}(3)(64) = 96\mathrm{ m}$ . Final velocity $= 24\mathrm{ m/s}$ .

Phase 2: $s_2 = 24 \times 12 = 288\mathrm{ m}$ .

Phase 3: $s_3 = \dfrac{1}{2}(24)(4) = 48\mathrm{ m}$ .

Total $= 96 + 288 + 48 = 432\mathrm{ m}$ .

(b) Find the average speed.

Total time $= 8 + 12 + 4 = 24\mathrm{ s}$ .

Average speed $= \dfrac{432}{24} = 18\mathrm{ m/s}$ .

Question 2 (Paper 2 style)

A stone is thrown horizontally from a cliff $80\mathrm{ m}$ high with a speed of $15\mathrm{ m/s}$ .

(a) Find the time to reach the ground.

Vertical: $h = \dfrac{1}{2}gt^2 \implies 80 = \dfrac{1}{2}(9.81)t^2 \implies t = \sqrt{\dfrac{160}{9.81}} \approx 4.04\mathrm{ s}$ .

(b) Find the horizontal distance from the base of the cliff.

X = 15 \times 4.04 = 60.6\mathrm\{ m\}

(c) Find the velocity (magnitude and direction) just before impact.

Horizontal: $v_x = 15\mathrm{ m/s}$ (constant).

Vertical: $v_y = gt = 9.81 \times 4.04 = 39.6\mathrm{ m/s}$ .

V = \sqrt\{15^2 + 39.6^2\} = \sqrt\{225 + 1568.2\} = \sqrt\{1793.2\} \approx 42.4\mathrm\{ m/s\}

\theta = \arctan\!\left(\frac\{39.6\}\{15\}\right) = \arctan(2.64) \approx 69.3\degree \mathrm\{ below horizontal\}

Question 3 (Paper 1 style)

A projectile is launched from ground level with speed $25\mathrm{ m/s}$ at an angle of $50\degree$ above the horizontal.

(a) Calculate the maximum height.

H = \frac\{(25\sin 50\degree)^2\}\{2(9.81)\} = \frac\{(19.15)^2\}\{19.62\} = \frac\{366.7\}\{19.62\} \approx 18.7\mathrm\{ m\}

(b) Calculate the range.

R = \frac\{25^2 \sin 100\degree\}\{9.81\} = \frac\{625 \times 0.9848\}\{9.81\} \approx 62.7\mathrm\{ m\}

Question 4 (Paper 2 style)

A ball is dropped from rest from a height of $20\mathrm{ m}$ . At the same instant, a second ball is Thrown vertically upward from the ground with speed $v$ .

Determine the value of $v$ for which the two balls meet at a height of $10\mathrm{ m}$ .

Ball 1 (dropped): $y_1 = 20 - \dfrac{1}{2}gt^2$

At $y_1 = 10$ : $10 = 20 - 4.905t^2 \implies t^2 = \dfrac{10}{4.905} \implies t = 1.428\mathrm{ s}$ .

Ball 2 (thrown up): $y_2 = vt - \dfrac{1}{2}gt^2$

At $y_2 = 10$ when $t = 1.428$ :

10 = v(1.428) - 4.905(1.428)^2

10 = 1.428v - 10

1.428v = 20 \implies v = 14.0\mathrm\{ m/s\}

Intuition

Kinematics is the storytelling of motion. A displacement-time graph tells you where something has been, while a velocity-time graph tells you how fast it is going and how quickly it is changing. Projectile motion is the elegant result of two independent stories playing out simultaneously: horizontal motion at constant speed and vertical motion under gravity, like a ball rolling off a table while simultaneously falling. The SUVAT equations are the shorthand for these stories when acceleration stays constant, and calculus takes over when it does not.

Summary

Quantity	Symbol	SI Unit
Displacement	$s$	m
Velocity	$v$	m/s
Acceleration	$a$	m/s $^2$
Time	$t$	s
Gravitational acceleration	$g$	9.81 m/s $^2$

SUVAT Equation	Use When
$v = u + at$	No displacement needed
$s = ut + \frac{1}{2}at^2$	No final velocity needed
$v^2 = u^2 + 2as$	No time needed
$s = \frac{1}{2}(u+v)t$	No acceleration needed

A boat can travel at $4\mathrm{ m/s}$ in still water. It needs to cross a river $100\mathrm{ m}$ Wide flowing at $3\mathrm{ m/s}$ .

(a) If the boat heads directly across, how far downstream does it land?

Time to cross: $t = \dfrac{100}{4} = 25\mathrm{ s}$ .

Downstream drift: $d = 3 \times 25 = 75\mathrm{ m}$ .

(b) What heading should the boat take to land directly across?

The boat must angle upstream so that the upstream component of its velocity cancels the current:

4\sin\theta = 3 \implies \theta = \arcsin(0.75) = 48.6\degree

The boat heads $48.6\degree$ upstream from the perpendicular.

Velocity across: $v_{\mathrm{across}} = 4\cos 48.6\degree = 2.65\mathrm{ m/s}$ .

Time to cross: $t = \dfrac{100}{2.65} = 37.7\mathrm{ s}$ .

Non-Uniform Acceleration

When acceleration is not constant, use calculus:

A = \frac`\{dv}, \{dt}` \implies v = \int a\,dt

V = \frac`\{ds}, \{dt}` \implies s = \int v\,dt

And conversely:

V = \frac`\{ds}, \{dt}`\quad a = \frac`\{dv}, \{dt}` = \frac\{d^2s\}\{dt^2\}

A particle moves with acceleration $a = 6t\mathrm{ m/s}^2$ . At $t = 0$ , $v = 2\mathrm{ m/s}$ and $s = 0$ .

V = \int 6t\,dt = 3t^2 + c

$v(0) = 2 \implies c = 2$ So $v = 3t^2 + 2$ .

S = \int (3t^2 + 2)\,dt = t^3 + 2t + d

$s(0) = 0 \implies d = 0$ So $s = t^3 + 2t$ .

Graphical Analysis Extended

Velocity-Time Graphs for Non-Uniform Acceleration

For a curved velocity-time graph:

The gradient at any point gives the instantaneous acceleration.
The area under the curve gives the displacement.
Use integration for the area: $s = \displaystyle\int_{t_1}^{t_2} v(t)\,dt$ .

Acceleration-Time Graphs

The area under an acceleration-time graph gives the change in velocity.
$\Delta v = \displaystyle\int_{t_1}^{t_2} a(t)\,dt$ .

Motion in One Dimension: Advanced Problems

Stopping Distance

The total stopping distance of a vehicle consists of:

Thinking distance: distance travelled during the driver’s reaction time.
$d_{\mathrm{think}} = v \times t_r$
Braking distance: distance travelled while braking. $d_{\mathrm{brake}} = \frac{v^2}{2a}$

Total stopping distance $= d_{\mathrm{think}} + d_{\mathrm{brake}}$ .

A car travels at $30\mathrm{ m/s}$ ( $108\mathrm{ km/h}$ ). The driver’s reaction time is $0.7\mathrm{ s}$ and the maximum deceleration is $8\mathrm{ m/s}^2$ .

D_\{\mathrm\{think\}\} = 30 \times 0.7 = 21\mathrm\{ m\}

D_\{\mathrm\{brake\}\} = \frac\{30^2\}\{2 \times 8\} = \frac\{900\}\{16\} = 56.25\mathrm\{ m\}

D_\{\mathrm\{total\}\} = 21 + 56.25 = 77.25\mathrm\{ m\}

Question 5 (Paper 2 style)

A ball is thrown from the top of a $40\mathrm{ m}$ building with initial velocity $15\mathrm{ m/s}$ at $30\degree$ above the horizontal.

(a) Find the time for the ball to reach the ground.

Vertical: $s_y = u_y t - \dfrac{1}{2}gt^2$

-40 = 15\sin 30\degree \cdot t - 4.905t^2

-40 = 7.5t - 4.905t^2

4.905t^2 - 7.5t - 40 = 0

T = \frac\{7.5 \pm \sqrt\{56.25 + 784.8\}\}\{9.81\} = \frac\{7.5 \pm 28.97\}\{9.81\}

T = \frac\{36.47\}\{9.81\} = 3.72\mathrm\{ s\}

(b) Find the horizontal range.

X = 15\cos 30\degree \times 3.72 = 12.99 \times 3.72 = 48.3\mathrm\{ m\}

(c) Find the velocity (magnitude and direction) when the ball hits the ground.

Horizontal: $v_x = 15\cos 30\degree = 12.99\mathrm{ m/s}$ .

Vertical: $v_y = 7.5 - 9.81(3.72) = 7.5 - 36.49 = -28.99\mathrm{ m/s}$ .

V = \sqrt\{12.99^2 + 28.99^2\} = \sqrt\{168.7 + 840.4\} = \sqrt\{1009.1\} = 31.8\mathrm\{ m/s\}

Which expression gives $v$ ?

A. $\sqrt{2gH}$ B. $\sqrt{2g(H-h)}$ C. $\sqrt{2gH - 2gh}$ D. $\sqrt{2g(H+h)}$

Answer: B. From energy conservation: $\dfrac{1}{2}mv^2 = mg(H-h)$ So $v = \sqrt{2g(H-h)}$ .

Question 7 (Paper 2 style)

Two cars are travelling on a straight road. Car A is travelling at a constant speed of $20\mathrm{ m/s}$ . Car BInitially at rest $50\mathrm{ m}$ behind Car AAccelerates at $2\mathrm{ m/s}^2$ .

(a) How long does it take for Car B to catch up with Car A?

Let $t = 0$ when Car B starts. Car A has a $50\mathrm{ m}$ head start.

Position of Car A: $s_A = 20t + 50$

Position of Car B: $s_B = \dfrac{1}{2}(2)t^2 = t^2$

When $s_A = s_B$ : $t^2 = 20t + 50 \implies t^2 - 20t - 50 = 0$ .

T = \frac\{20 \pm \sqrt\{400 + 200\}\}\{2\} = \frac\{20 \pm 24.49\}\{2\}

$t = 22.25\mathrm{ s}$ .

(b) What is the speed of Car B at this moment?

V_B = 2 \times 22.25 = 44.5\mathrm\{ m/s\}

Kinematics in Two Dimensions: Vector Approach

Vector Notation for Motion

Position vector: $\vec{r}(t) = x(t)\hat{i} + y(t)\hat{j}$

Velocity: $\vec{v}(t) = \dfrac{d\vec{r}}{dt} = \dot{x}(t)\hat{i} + \dot{y}(t)\hat{j}$

Acceleration: $\vec{a}(t) = \dfrac{d\vec{v}}{dt} = \ddot{x}(t)\hat{i} + \ddot{y}(t)\hat{j}$

Speed and Velocity

Speed is the magnitude of velocity:

|`\vec{v}`| = \sqrt\{v_x^2 + v_y^2\}

Displacement as a Vector

The displacement from $t_1$ to $t_2$ is:

\Delta\vec\{r\} = \vec\{r\}(t_2) - \vec\{r\}(t_1)

Uniformly Accelerated Motion in Two Dimensions

When acceleration is constant (both magnitude and direction), the SUVAT equations can be applied Separately to each component.

Equations

V_x = u_x + a_x t, \quad v_y = u_y + a_y t

X = u_x t + \frac\{1\}\{2\}a_x t^2, \quad y = u_y t + \frac\{1\}\{2\}a_y t^2

Projectile Motion Revisited (Vector Form)

For a projectile launched with initial velocity $\vec{u} = u\cos\theta\,\hat{i} + u\sin\theta\,\hat{j}$ :

$a_x = 0$ , $a_y = -g$

X(t) = u\cos\theta \cdot t

Y(t) = u\sin\theta \cdot t - \frac\{1\}\{2\}gt^2

V_x(t) = u\cos\theta

V_y(t) = u\sin\theta - gt

Question 8 (Paper 2 style)

A particle moves along a straight line. Its acceleration is given by $a = 4 - 2t\mathrm{ m/s}^2$ .

(a) Find the time when the particle is momentarily at rest.

V = \int_0^t (4-2t')\,dt' = 4t - t^2

When $v = 0$ : $t(4 - t) = 0 \implies t = 0$ or $t = 4\mathrm{ s}$ .

(b) Find the displacement at $t = 4\mathrm{ s}$ .

S = \int_0^4 (4t - t^2)\,dt = \left[2t^2 - \frac\{t^3\}\{3\}\right]_0^4 = 32 - \frac\{64\}\{3\} = \frac\{32\}\{3\}\mathrm\{ m\}

Question 9 (Paper 1 style)

A ball is projected at speed $v$ at angle $\theta$ above horizontal on level ground. For what value of $\theta$ is the horizontal range maximised?

The range is $R = \dfrac{v^2 \sin 2\theta}{g}$ . This is maximised when $\sin 2\theta = 1$ I.e., $2\theta = 90\degree$ So $\theta = 45\degree$ .

Question 10 (Paper 2 style)

An object is released from a hot air balloon ascending at $5\mathrm{ m/s}$ . At the moment of Release, the balloon is at a height of $120\mathrm{ m}$ .

(a) Find the maximum height reached by the object.

At release: $u_y = 5\mathrm{ m/s}$ , $s_y = 120\mathrm{ m}$ .

V_y^2 = u_y^2 - 2g \cdot \Delta s \implies 0 = 25 - 2(9.81)\Delta s

\Delta s = \frac\{25\}\{19.62\} = 1.27\mathrm\{ m\}

Maximum height $= 120 + 1.27 = 121.3\mathrm{ m}$ .

(b) Find the time to reach the ground.

S = 120 + 5t - 4.905t^2

At ground: $4.905t^2 - 5t - 120 = 0$ .

T = \frac\{5 + \sqrt\{25 + 2354\}\}\{9.81\} = \frac\{5 + 48.72\}\{9.81\} = 5.48\mathrm\{ s\}

(c) Find the velocity just before impact.

V_y = 5 - 9.81(5.48) = 5 - 53.76 = -48.76\mathrm\{ m/s\}
