## Second Law of Motion

Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balance. It also states that the acceleration of an object is dependent upon two variable- the net force acting upon the object and the mass of the object. The accelertation of an object depneds directly upon the net force acting upon the object, and inversely upon the mass of the object. A the force acting upon an object is increased, the acceletration of the objects increased. As the mass of an object is increased, the acceleration of the object is decreased

Pushing a ball is an example, the velocity goes from0 to how hard you push the ball. This law also states that if it gets twice the mass it accelerates half as much. An examples is pushing a 10 lb ball as hard as you can, then pushing a 5 lb ball as hard as you can. The 10 lb ball would accelerate less than the 5 lb ball be cause the 10 lb ball has a higher mass. | If two dogs are on each side then the total force pulling to the left balances the total force pulling to the right. That means the net force on the sled is zero, so the sled doesn't move. | An apple falling to the ground must be under the influence of a force, according to the second law of motion. That force is gravity, which causes the apple to accelerate towards earth's center. |

If two dogs are on each side then the total force pulling to the left balances the total force pulling to the right. That means the net force on the sled is zero, so the sled doesn't move.

## How this law occurs in our everyday life.

Swimming is a perfect example of how this law occurs in our everyday lives. Many swimmers tend to push off the wall of a pool to get a speedy start. The force in this situation is the pushing from your legs, which causes your body to accelerate in the direction of the push.
