Velocity Potential Energy :. Potential energy is called the energy of position. Energy that is dependant on height is called gravitational potential energy.
The formula for potential energy is:. Weight mass x gravity determines the amount of potential energy. Is there potential energy in the 5 forms of energy? Yes, potential energy can be found in fossil fuels, within the foods you eat, and the batteries that you use. Conservation of Energy :.
It is important to understand that each form of energy does not exist separately but undergoes change from one to another without a net loss in energy. Consider this example:. As a projectile is launched into the air KE is at its maximum. As the projectile gains altitude PE becomes greater than KE.
At the top of its arc, PE is at its maximum. The whole cycle reverses itself on the way down. As you can see, the loss in KE is a gain in PE. Heat, or thermal energy, can be transferred by convection, conduction, and radiation.
When water boils, thermal energy is transferred by conduction as molecules vibrate. Magnetic fields are the effect of electric currents and magnetic materials specified by the direction and strength of attraction or repulsion. All forms of kinetic energy are the result of a previous state of potential energy.
For example, the stored chemical potential energy of a battery converts to electrical kinetic energy to transport electricity to a light bulb, which radiates thermal kinetic energy.
Potential and Kinetic Energy Explained. Overview Energy can neither be created nor destroyed, this is the conservation of energy law. All energy, whether potential or kinetic, is measured in Joules J.
Potential Energy Potential Energy is defined as the energy stored by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors. Types of Potential Energy Chemical Battery animation motions towards a full charge. Elastic Spring animation expands and compresses. Nuclear Electrons circle a nucleus at the atomic level.
Gravitational Apple falls from tree and rolls behind the trunk. Kinetic Energy Kinetic Energy is defined as energy that a body possesses by virtue of being in motion. Types of Kinetic Energy Mechanical Gear spinning.
Electrical Light bulb emitting light rays. Thermal Water-drop shaped flame sways left to right. Magnetic Compass needle rotates directionally. Kinetic And Potential Energy Working Together All forms of kinetic energy are the result of a previous state of potential energy.
