When a heavy coin falls a short distance towards the ground it does not reach terminal velocity. Why is this?

• The coin has not hit the ground.

• The weight of the coin equals the air resistance.

• The weight of the coin increases as air resistance increases.

• The weight of the coin is always more than air resistance.

The speed-time graph for a falling skydiver is shown below. As he falls, the skydiver spreads out his arms and legs and then opens his parachute. Which part of the graph shows the skydiver falling with terminal velocity?

• A

• B

• C

• D

The diagram shows the speed-time graph of the motion of a car for four seconds.

• 15m

• 25m

• 30m

• 40m

An object moves from P to Q in 10s with uniform acceleration.

velocity at P = 5 m/ s

velocity at Q = 12 m/ s

What is the acceleration?

• 0.5 m/s/s

• 0.7 m/s/s

• 1.2 m/s/s

• 1.7 m/s/s

The graph shows how the height of an object above the ground changes with time.

What is the terminal velocity?

• 1 m/s

• 1.3 m/s

• 1.6 m/s

• 2 m/s

The speed-time graph represents the journey of a car. The dots separate different sections of the journey. There are six different sections.

How many sections represent the car moving with non-uniform acceleration?

• 1

• 2

• 3

• 4

A steel ball is released just below the surface of thick oil in a cylinder.

During the first few centimetres of travel, what is the acceleration of the ball?

• constant and equal to 10 m/s/s

• constant but less than 10 m/s/s

• decreasing

• increasing

A cyclist travels along a hilly road without using the pedals or brakes. Air resistance and friction are negligible. The speed/ time graph of the cyclist is shown.

At which point did he reach the bottom of the first hill?

• A

• B

• C

• D
