Energy- Energy is the ability to do work.Things that are in motion.

You maybe wonder why you can move and run or do things freely. This is because of energy. Imagine the world without energy. Maybe you can't, because how can you imagine without energy? Well, it's up to you to think about it. Let's proceed to the classification of energy.

Classification of Energy

1. Kinetic energy

Kinetic energy is the energy of motion

Examples:

Moving car
Running Machine

2. Potential energy.

Potential energy -the object that is not moving.

Examples:

A car that is not moving
A park bike

Forms of energy

a. Electrical energy

Electrical energy is an energy that comes from generated power or from a lightning wave.

Examples:

Generators,water turbine, and dynamo

b. Mecahnical energy

Mechanical energy is an energy that derived from machine.

Examples:(ads2)

Engine, water mill and grinder

c. Light energy

Light energy is energy that comes from a light source.

Examples:

sunlight,flourescent,bulb,laser,and beam

d. Sound energy

Sound energy is an energy produced by vibrating bodies.

Examples:

Sonic boom,sound waves and noise

e. Heat energy

Heat energy is an energy of moving molecules.

Examples:

fuel,heat from the sun, and heat from the fire
