Energy is the ability to cause change or do WORK. WORK is to make something MOVE by applying FORCE to it. There are 7 Types of Energy that can cause things.

Energy is said to be the ability to do work. That means the ability to make something happen. By “happen” it means to make things move or change condition.

Kinetic and Potential Energy have many forms. 1. Mechanical Energy - Energy associated with motion or position.

Forms of Energy. Nature of Energy Energy is the ability to do work. If an object or organism does work, then it uses energy. Work is the use of a force.

Energy is the ability to do WORK. WORK is to make something MOVE by applying FORCE to it. There are 7 Forms of Energy that can cause things to MOVE, or do WORK.

The 7 Forms of Energy can be remembered using this acronym: ACHELMS

It is also the energy used in nuclear bombs and nuclear power plants. ACHELMS ATOMIC ENERGY is the energy created when the NUCLEUS of ATOMS join together or split apart. It is also the energy used in nuclear bombs and nuclear power plants.

ACHELMS CHEMICAL ENERGY the energy stored in a substance that is released during a chemical reaction. Burning chemicals in fuel to make heat Using chemicals in batteries to operate a toy Digestion of chemicals in food to give things energy

ACHELMS HEAT HEAT ENERGY the energy of the particles (atoms) that make up an object. The faster the particles move the more heat/THERMAL energy that is created.

ACHELMS ELECTRICAL ENERGY the energy of moving ELECTRONS. Electrons moving through the wires of radios, TVs, lights and all electrical appliances are examples of electrical energy.

ACHELMS LIGHT ENERGY the energy caused by the vibration of electrically charged particles. Light/radiant energy is often visible like sunlight, starlight and electrical lights. STARS

ACHELMS MECHANICAL ENERGY the energy of MOVING objects. Any MOTION or MOVING object has mechanical energy riding a bike swinging a hammer a spinning windmill

ACHELMS SOUND ENERGY the energy from the vibration of an object. A guitar string vibrates to make sound. Vocal chords vibrate make sound. These vibrations cause the air particles to vibrate.

ALL 7 Forms of Energy can be either POTENTIAL OR KINETIC A guitar string being pulled back is potential sound energy. When the guitar string is released, it is changed to kinetic sound energy.

A CHANGE in one type of energy to another is called an ENERGY CONVERSION
