To give examples of objects having kinetic energy. To analyse situations and distinguish if objects possess kinetic energy or not. To understand the two factors affecting kinetic energy. To give the equation of kinetic energy for solving numerical problem...

 Sir Issac Newton formulated the three laws of motion in physics.  Newton's first law - Every body continues in its state of rest or of uniform motion unless an unbalanced external force acts on it.  Newton's second law - The rate of change of momentum of a body is directly proportional to unbalanced external force acting on it.  F=ma, m is the mass and a is the acceleration  Newton's third law- For every action  there is an equal and opposite reaction.  For detailed description  click here
