Two runners take part in a race. The graph shows how the speed of each runner changes with time. What does the graph show about the runners at time t?

• Runner 1 is overtaking runner 2.

• Runner 1 has zero acceleration.

• Runner 2 is slowing down.

• Both runners are moving at the same speed.

A force acting on a moving ball causes its motion to change. This force stays constant. What makes the force produce a greater change in the motion of the ball?

• increasing the temperature of the ball

• decreasing the total mass of the ball

• using a ball with a hollow centre but the same mass

• using a different material for the ball so that it has a lower density but the same mass
