Plan a simple investigation to show how a ball's motion changes when you push it harder.

• Push the ball gently and observe its motion.

• Push the ball with different strengths and measure the distance it travels each time.

• Drop the ball from a height and see how it bounces.

• Roll the ball down a slope and measure its speed.

Design an experiment to show how the position of a ball changes when it is pushed on different surfaces.

• Push the ball on a smooth surface and a rough surface, and measure how far it travels on each.

• Drop the ball from a height and measure how high it bounces.

• Spin the ball and observe how long it spins.
