# Newton's 3 Laws of Motion

### By: Baylee Jones

## Objects in motion tend to stay in motion unless acted upon by an outside force.

The first law states that if the net force is zero, then the velocity of the object is constant. Velocity is a vector quantity which expresses both the object's speed and the direction of its motion; therefore, the statement that the object's velocity is constant is a statement that both its speed and the direction of its motion are constant.

If you put it into real life terms then lets compare it to a truck. So,If it's not in park, it will just keep rolling rolling rolling unless there is an opposing force added.

## Force is directly related to mass and acceleration... the heavier the object, the more force is required to move it.

The second law states that the net force on an object is equal to the rate of change.The second law can also be stated in terms of an object's acceleration. Since the law is valid only for constant-mass systems, the mass can be taken outside the differentiation operator by the constant factor rule in differentiation.

Newton's second law requires modification if the effects of special relativity are to be taken into account, because at high speeds the approximation that momentum is the product of rest mass and velocity is not accurate.

If you put in into real life terms then lets compare it to a truck. So, Your buddies would much rather push a car than a truck.

## For every action there is an equal and opposite reaction.

The third law states that all forces exist in pairs: if one object *A* exerts a force **F***A* on a second object *B*, then *B* simultaneously exerts a force **F***B* on *A*, and the two forces are equal and opposite.The third law means that all forces are interactions between different bodies, and thus that there is no such thing as a unidirectional force or a force that acts on only one body.The two forces in Newton's third law are of the same type (e.g., if the road exerts a forward frictional force on an accelerating car's tires, then it is also a frictional force that Newton's third law predicts for the tires pushing backward on the road).

If you put it into real life terms then lets compare it to a truck. So, If you don't take care of your truck, it won't take care of you.
