NEWTON’S LAW OF MOTION

Isaac Newton had introduced three laws of motion. The very interesting facts proved by Isaac Newton in these laws which we use to see in our daily life.

FIRST LAW

Newton’s first law of motion is also known as law of inertia. It states that “A body at rest remains at rest, and a body at motion remains in motion unless any external force applied on it”.Newtons Law of Motion1-engineeringprayog

The above statement means that any object or a body cannot stop or start without any external force.

SECOND LAW

It states that “The rate of change of momentum of a body, is directly proportional to the force applied on it”.

F=ma

 

Where, F – force applied on a body

m- mass of the body

a- acceleration

THIRD LAW

It states that “For every action, there is equal and opposite reaction”.
