# Newtons Laws of Motion

## Newton's 1st Law of Motion

An object in rest stays in rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced forced.

An application for this law are if your in a car going 65 mph and not wearing a seatbelt and you hit the brakes and fly through the wind shield and then hit a wall.

## Newton's 2nd Law of Motion

Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

An application for this law is a man pushing a box he is applying force to the box which then accelerates.

## Newton's 3rd Law of Motion

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

An application for this law is A bird pushes air down while flying, Since forces result from similar interactions, the air must also be pushing the bird upwards. This allows the bird to fly.
