Question

what is a energy and type of energy

Answer 1

The capacity for doing work. It may exist in potential,kinetic,thermal,electrical,chemical,nuclear or other forms of energy.

Answer 2

$\huge{\underline{\tt{\green{Energy-}}}}$ It is a ability or capacity to do work.

• Unit - Joule

Mainly there are 3 types of Energy, Let's discuss them -

Kinetic energy - It is a energy stored in a body due to its motion.

• Formula $\longrightarrow \tt \frac{ 1}{2}{MV}^{2}$

Potential energy - It is a energy stored in a body due to its position and confrigairon.

• Formula $\longrightarrow\tt{Mgh}$

Mechanical energy - It is sum of kinetic energy and potential energy.

• Formula $\longrightarrow \tt \frac{ 1}{2}{Mv}^{2}+{Mgh}$

Law of conservation of energy - Total energy of a system always remains constant. Energy nor be created nor be destroyed. It can only convert to one form to other.
