Use a different ball in the experiment.
Throw the ball three more times.
Change the height from which the ball is thrown.
Leigha pushes a toy car lightly, causing it to move toward her brother. If the next time, Leigha pushed the car harder, what will happen?
The car will move slower.
The car won't move.
The car will move more quickly than with the light push.
The car will move at the same speed as with the light push.
