Match the following examples of energy with the primary form of energy exhibited.

friction:

nuclear power plant:

toaster element:

welding torch:

eraser sitting on a desk edge:

light bulb:

campfire:

moving car:

lump of coal in a storage bin:

stick of TNT:

Options are nuclear, heat, kinetic, potential, light, and solar energy

The primary energy exhibited is:

friction: Heat energy

Due to friction. there is heat loss in mostly all machines.

nuclear power plant: Nuclear energy

In nuclear power plant, fission or fusion of radio-active substances produces large amount of nuclear energy.

toaster element: Heat energy

Heat energy is produced in the toaster when electricity passes through the element. This is used to heat the toasts.

welding torch: Heat energy

The heat energy produced in the welding torch is used in welding.

eraser sitting on a desk edge: Potential energy

Potential energy is possessed by a body due to virtue of its height.

light bulb: Heat energy and light energy.

The element inside the bulb gets heated first and then light energy is produced.

campfire: Heat energy

Heat is produced and then light energy in case of campfire.

moving car: Kinetic energy

A moving body has kinetic energy.

lump of coal in a storage bin: Potential energy

A lump of coal in a storage bin has potential energy.

stick of TNT: potential energy

Stick of TNT is formed of explosive mixture. It contains potential energy.
