A
force is a push or pull that can make things move, stop, or change direction.
Imagine kicking a soccer ball. Your foot applies a force that makes the ball
move forward. If you push a toy car across the floor, your hands exert a force
on it. The car starts moving because of this force. Forces can also stop
objects from moving. If you kick a soccer ball and then stop, the ball
eventually stops too because no force is pushing it anymore.
