5 m s^–2
8 m s^–2
20 m s^–2
35 m s^–2

Question 3

Marks: 1

What is the definition of acceleration?

The length between two points
The length between two points in a certain direction
The rate of change of displacement
The rate of change of velocity

Question 4

Marks: 1

sl-mcq-2-1-easy-q5

Which property of the graph represents the total displacement of the object?

The gradient of the line
The total area between the line and the axis
The y-intercept
The x-intercept

Question 6

Marks: 1

What does the gradient of a displacement-time graph represent?

Distance
Speed
Velocity
Acceleration

Question 7

Marks: 1

A luxurious speed boat travels down the French Riviera with an initial velocity of 10 m s^–1. The owner wishes to show off the power of its engine, accelerating at a rate of 2 m s^–2 for 5 seconds. What is the final velocity of her speed boat?

20 m s^–1
22 m s^–1
24 m s^–1
26 m s^–1

Question 8

Marks: 1

The graph below shows the motion of a skydiver in free fall.

2-1-q8-sl-easy-mcq-phy

What point on the graph represents the skydiver reaching terminal velocity?

Question 9

Marks: 1

A ball is thrown upward with an initial velocity of +3 m s^–1. What SUVAT equation will correctly calculate the maximum height reached by the ball?

$v = u + a t$
$s = u t + \frac{1}{2} a t^{2}$
$v^{2} = u^{2} + 2 a s$
$s = \frac{(v + u) t}{2}$
