# Newton's Laws of Motion

## Newton's 1st Law of Motion

Newton's first law states that an object in motion stays in motion unless acted upon by an outside force while an object at rest stays at rest unless acted upon by an outside force.

In this image we see that the object (ball) will stay at rest until an outside force (human) comes and acts upon it (kicks it). The ball then stays in motion (flying through the air) until an outside force (the wall) acts upon it and stops it's motion.

## Newton's 2nd Law

Newton's 2nd law tells us that an object will have greater acceleration if a greater force is applied to it. Therefore, the mass of an object and the force applied to it will affect acceleration. This law states that the acceleration (A) of an object equals net force (F) divided by mass (M) and can be calculated using the equation F=MA.

## Newton's 3rd Law of Motion

Newton's final law states that when one object exerts a force on a second object, the second object exerts a force on the first that is equal in strength and opposite in direction.

In this image we see that the boys action is letting go of the ball, then the ball exerts an equal force and bounces back up.
