Question

State the S.I unit of energy.

Answer 1

Hint: Energy is the quantitative property that must be converted to a body or physical system to work done on the body, or to heat it.
Energy maintains conservation law.
The conservation of energy means that energy can be transferred in form, but can not be created or destroyed.

Complete step by step solution:
The general types of energy are the kinetic energy of a moving object, the potential energy which is stored by an object. When fuel burns the chemical energy is released the radiant energy carried by light and the thermal energy due to the temperature of an object.
Generally, energy is described as the capability to do work; it is the power derived from the utilization of physical or chemical resources, especially to provide light and heat or to work machines.
We know that Einstein's famous equation:
$E=m{c}^2$
Here,
$E$ is energy
$M$ is mass
$c$ is the speed of light
Energy exists in many forms such as mechanical, electric, magnetic, gravitational, chemical, gravitational, chemical, ionization, nuclear, thermal, sound wave, chronodyn, elastic, radiant, and lots more.
Finally, $$Joule$$ is the S.I unit of energy.

Note:
The total energy of a system can be divided into two types, they are potential energy, kinetic energy, or combinations of the two in various ways.
The movement of an object or the composite motion of the components of an object is known as the kinetic energy
Potential energy reflects the potential of an object that has motion, and it is a function of the position of an object within a field or may be stored in the field itself.
