Work And Energy – Energy
Energy is defined as the capacity to do work.
The various forms of energy include kinetic energy, potential energy, thermal or heat energy, electrical energy and chemical energy.
Energy stored in an object due to its position or place is known as potential energy.
The gravitational potential energy of an object is the work done in raising it from the ground to a certain point against gravity. It is calculated using the expression PE= mgh.
The energy possessed in a moving object is called kinetic energy. It is calculated by the formula:
EK = mv2
