In physics, energy is defined as the ability to do work or the capacity for change. It is a scalar physical quantity that is measured in joules (J) or other units such as electronvolts (eV). Energy can take many forms, including kinetic energy (the energy of motion), potential energy (the energy of position or configuration), thermal energy (the energy of heat), chemical energy (the energy stored in chemical bonds), and electrical energy (the energy associated with the movement of charged particles).

Here are some examples of energy in real-life situations:

A roller coaster: A roller coaster converts potential energy to kinetic energy as it travels up and down hills. At the top of a hill, the coaster has high potential energy, and as it travels down the hill, this potential energy is converted into kinetic energy, which is the energy of motion.

A light bulb: A light bulb converts electrical energy into light and thermal energy. Electrical energy flows through the bulb's filament, which heats up and emits light as a result.

A battery: A battery stores chemical energy, which is converted into electrical energy when the battery is used to power a device such as a flashlight or a smartphone.

Energy is a fundamental concept in physics and is used to describe many natural phenomena.

The SI unit of Energy is joule [ J ]
