Students design an investigation using a spring launcher to launch a 15 9 ball

into the at“ For each trial, they compress the spring by a different amount before

releasing It. Then they measure and record how far the ball goes before it hits the

ground.

This experiment can be used to determine —

• how the mass of an object affects the distance it moves

• how the mass of an object affects the force needed to move it

• how the force used to push an object affects the distance it moves

• how the size of an object affects the force needed to move it
