Newton’s Laws Of Motion & Conservation Laws
-
What Is Newton’s First Law Of Motion?
Newton’s 1st law: Every body persists in a state of rest or of uniform motion along a straight line (i.e. with constant velocity) unless and until it is acted upon…
-
What Is Newton’s Second Law Of Motion?
Newton’s 2nd law: The rate of change of momentum is directly proportional to the impressed force and is in the same direction along which the force acts. The magnitude is…
-
What Is Newton’s Third Law Of Motion
Newton’s 3rd law: To every action, there is always an equal and opposite reaction. If a particle 1 acts on particle 2 with a force in the direction along the…

What Is Conservative Force Field?
Conservative force field: Let us consider a particle is acted upon by a force , as a result the particle is displaced by a distance . Then the work done…
-
What Is A Non-Conservative Force Field?
Non-conservative force: If there is no scalar function V in such a way that , i.e. the force cannot be expressed as the gradient of a scalar function, then the…
-
What Is Work?
Work: When a force acting on a body, physically displaces the body through a distance in the direction of the force, then it is said that work is done by…
-
What Is Power?
Power: The time rate of doing work on a particle is called instantaneous power. Power is represented by the P as , where W is the work done by the…

What Is Kinetic Energy?
Kinetic Energy; The kinetic energy of an object is the energy that the object possesses by virtue of its motion. For example, when a bullet is fired from a revolver,…
