Isaac Newton and His law

Who is Sir Isaac Newton?
Image result for isaac newtonSir Isaac Newton was an English mathematician, physicist, astronomer, theologian, and author who is widely recognized as one of the most influential scientists of all time, and a key figure in the scientific revolution.

Isaac Newton's 3 laws:
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. The key point here is that if there is no net force acting on an object

The second law explains how the velocity of an object changes when it is subjected to an external force. The law defines a force to be equal to change in momentum per change in time.

The third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal force on object A.
