Energy and its types ?

Energy is the ability to do work or cause change. Without energy, nothing would move, grow, or change. Energy cannot be created from nothing, nor can it be destroyed — it can only be transformed from one form to another.

Types of Energy

Kinetic Energy (KE):
The energy an object possesses because of its motion. The faster an object moves and the greater its mass, the more kinetic energy it has.
Formula: KE = ½ mv² (m = mass, v = velocity)

Potential Energy (PE):
Energy stored in an object due to its position or condition. It includes different types:

Gravitational Potential Energy:
Energy due to an object's height above the ground. A boulder on a mountain has high gravitational PE.
Formula: PE = mgh (m = mass, g = gravity, h = height)

Elastic Potential Energy:
Energy stored in a stretched or compressed elastic object (e.g., a stretched rubber band or compressed spring).

Chemical Potential Energy:
Energy stored in the bonds of chemical compounds (e.g., food, fuel, batteries).

Thermal Energy (Heat):
The total kinetic energy of all the moving particles in a substance. The hotter the object, the greater its thermal energy.

Light Energy (Radiant Energy):
Energy carried by electromagnetic waves, including visible light, ultraviolet (UV), and infrared radiation. The Sun is the main source of light energy on Earth.

Sound Energy:
Energy produced by vibrating objects and transmitted through waves in a medium (air, water, solid). Sound cannot travel through a vacuum.

Electrical Energy:
Energy due to the movement of electric charges (electrons) through a conductor. Powers homes, machines, and devices.

Nuclear Energy:
Energy stored in the nucleus of an atom. Released through nuclear fission (splitting of nuclei) or nuclear fusion (joining of nuclei). This is the energy source of the Sun and nuclear power plants.

Mechanical Energy:

The sum of kinetic energy and potential energy of a moving object.
