# Newton's 3 Laws of Motion

## 1st Law of Motion

An object at rest will remain at rest unless acted upon by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by and unbalanced force. The law is often called "law of inertia"

## 2nd Law of Motion

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.
When a baseball player applies a large force to a baseball (when he hits

it) ... Hence they should be a net force for application of Newton's Second Law of Motion

Newton's Second Law of Motion

## 3rd Law of Motion

Newton's third Law of Motion states that for every action there is an equal and opposite reaction. ( examples are - bouncing a ball, jumping on a trampoline, and a fish using its fins to push water backwards)
