Pull It, Push It
... To move an object, you must exert a force. Tools and machines can also exert a force. They use a force to set something in motion. A force is a push or a pull. A push or a pull can cause an object to move. Once an object is moving, it needs a force to speed up, slow down, change direction, or sto ...
