ENERGY

What it is

Energy is the strength and vitality to make things do mental or physical activities. It Helps to make things move and work.

The Main Types

The main types of energy are Kinetic And Potential Energy. Kinetic energy is the energy being used and is in motion. Potential Energy is the energy of a body with respect to the position of the body or the arrangement of the particles of the system.

Other different types

Some other different types of energy are Thermal, Elastic, Gravitational,Electrical, Heat, chemical, Translational, And Rotational.

Some Facts about Kinetic

Kinetic energy is the most common type of energy, the kinetic energy of an object can be found as long as you know the objects mass and speed. An object keeps the same kinetic energy as long as it does not speed up or slow down. The unit when measuring kinetic energy is called a joule.

Facts about Potential Energy

There are two main types of potential energy: gravitational potential energy and elastic potential energy.

When an object is held in a vertical position, it has gravitational potential energy because gravity is working to pull it down.

The amount of gravitational potential energy an object has depends on its height above the ground and its mass.

The heavier an object and the higher it is above the ground, the more gravitational potential energy it has.

Height and gravitational potential energy are directly related meaning if one doubles, so does the other.

Elastic potential energy is energy stored in objects that can be stretched or compressed.

Objects such as trampolines, rubber bands, and bungee cords all have elastic potential energy.

The more an object can stretch the more elastic potential energy it has.

The term potential energy was first used by a Scottish engineer and physicist named William Rankine during the 19th century.

The concept of potential energy dates all the way back to Aristotle.

When a bow and arrow is used, potential energy from the archers hand is transferred to the bow when it is being pulled back.

Energy stored within fossil fuels is called chemical potential energy.

Potential energy is called "potential" because although it is stored, it has the potential to be used later.

Once an object is acted on by a force, its potential energy is then transformed into a different form of energy.

An object must be changed by some type of force in order to possess potential energy.
