KINETIC ENERGY:

Moving things have kinetic energy. The more mass a thing has and the faster it moves, the more kinetic energy it has. All moving things have kinetic energy, even very large things like planets, and very small ones like atoms.

GRAVITATIONAL ENERGY:

The gravitational potential energy is the potential energy that depends on the gravitational force associated with height.

ELECTRICAL ENERGY:

Electric power is a renewable energy obtained by the movement of electric charges.

ELASTICAL ENERGY:

The energy stored in the spring stretched or compressed or another elastic material is called elastic potential energy. Energy is stored in the spring if it is compressed or stretched. The elastic potential energy is the one that stores an object by virtue of being deformed.

 MAGNETICAL ENERGY:

Electromagnetic energy is the amount of energy stored in a region of space that can be attributed to the presence of an electromagnetic field, and is expressed in terms of the intensities of the magnetic field and electric field.

 Energy transfers

Energy can transfer or move from one store to another in different ways. Devices such as lamps and heaters may be involved, or processes such as combustion. For example, energy can be transferred:

• by heating

• by mechanically

• by electrically

• by radiation

HEATING:

Some objects are hotter than others. Energy is transferred from the hotter object to the cooler one, and the difference in temperature between them decreases.

MECHANICAL TRASNFER:

Energy can be transferred mechanically through the movement of the parts in machines, and when the motion or position of an object changes. Sound waves and seismic waves (formed during earthquakes) are mechanical waves that transfer energy through materials and from place to place.

ELECTRICAL TRANSFER:

Energy is transferred when an electrical circuit is complete. A simple circuit may consist of a battery, lamp and wires. Internal energy stored in the battery is transferred to moving charged particles in the wire.

TRANSFER BY RADIATION:

Visible light, infrared light, microwaves and radio waves are forms of radiation. They are carried by waves (although unlike sound, these are not mechanical waves and can travel through empty space). Electric lamps and burning fuels transfer visible and infrared light to the surroundings.

Conservation of energy

In science, a system is a set of things and the processes that happen in them and between them. Energy can be stored or transferred, but it cannot be created or destroyed. This means that the total energy of a system stays the same. The idea that the total energy has the same value before and after a change is called conservation of energy.

For example, an electric lamp might transfer radiant energy to the surroundings. Some of this will be visible light and some will be infrared red light, which increases the temperature of the surroundings. The amount of energy transferred from the lamp will be the same as the amount of energy transferred into the lamp because energy can never be created or destroyed.
