Question

1. List THREE kinds of ENERGY.

2. Besides Gravitational and Elastic, what other kinds of
POTENTIAL energy can you think of?

150 words needed.

Answer 1

1.  Some kinds of energies are thermal energy, radiant energy, chemical energy, nuclear energy, electrical energy, motion energy, sound energy, elastic energy and gravitational energy etc.

2. Potential energy is defined as any type of energy of a system which is due to specific position of particles present in the system. Besides gravitational and elastic energy there is potential energy between two charges due to electrostatic attraction, known as electric potential energy. Furthermore in thermodynamic system, enthalpy is also a form of potential energy which is defined as the total energy of the system due to specific position and orientation of the particles present in that system. In chemicals there is chemical potential energy. In nucleus we have nuclear potential energy due to nuclear forces.
