LAW’S OF NEWTON’S

Sir Issac Newton

                    Newton’s First Law of Motion        

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

                           Newton’s second law

Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

F =M × A where M is mass and A is acceleration

                        Newton’s third law

“For every action there is an equal and opposite reaction”.

Example : The rocket’s action is push down on the ground with the force of it’s engines and the reaction is that the ground pushes the rockets upwards with an equal force.
