Newton’s First Law of Motion An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This law is often called "the law of inertia".

Force – a push or a pull on an object. Push – the force moves the object away from you Pull – the force moves the object towards you

Force If an object is not moving, a force can make it start moving. The object will move in the same direction as the force that acts on it.

Force Recall that direction is the path that a moving object follows. Look at the soccer ball below. At first, it is not moving. If you kick the ball, you exert a force on it. The ball will start moving in the same direction as your kick.

Force can change the direction of an object’s motion. Suppose a soccer ball is rolling toward you. You can kick it back in the opposite direction, or you can kick it to your right.

Force can also change a moving object’s speed. A force applied in the same direction as the object’s motion tends to make the object move faster. A force applied in the opposite direction tends to make the object move more slowly or even stop moving.

Force Say a friend throws a baseball to you. If you use a bat to hit the ball, the force you apply to the ball changes its direction. You change the direction from toward you to away from you.

Force The greater the force is, the greater the change in motion it produces. Suppose you first hit the ball gently with a small force. It will move slowly, and it will move only a short distance away from you.

Force Then you use the bat to hit the ball much harder, with a greater force. The ball will move faster and farther away from you. In both cases, the force you apply to the ball changes its motion. But using a greater force makes the ball move at a greater speed and a greater distance than using a smaller force does.
