Definition:
A force is a push or a pull in a specific direction.

*A force can change the speed, and direction of an object.

*If an object is moving it can slow it down or stop it, but if the object is not moving it can make it move or it can stay stationary if the force is balanced.

*some forces may not make an object change directions or it's speed.

*a small amount of force on an object may not cause a large object to move. The larger the mass of an object the more that object resists to change its motion.

*friction is a force that acts on a moving object in the opposite direction that the object is moving in.friction will cause an object to slow down and eventually stop.
