capacity to do work
energy
cannot be made or destroyed
energy
energy acquired by an object upon which work is done
mechanical energy
two types of mechanical energy
potential energy & kinetic energy
it is energy possessed by object at rest
potential energy
gravitational potential energy and elastic energy
potential energy
energy possessed by an object at motion
kinetic energy
energy can neither be created nor destroyed- only converted from one form of energy to another
law of conservation of energy
rate of doing work
power
