Forms of EnergyEnergy is the ability to do work. Energy can make things move or change and can be

transferred from one form to another and from one object to another.

Energy comes in many different forms, including: o mechanical energy o electrical energy o heat energy o light energy o sound energy (acoustic energy) o chemical energy

Mechanical Energy

Mechanical Energy is the energy that an object has due to its motion or position. Mechanical Energy encompasses two types of

energy:o Potential Energy (energy of position) – stored

energy. Energy that is not causing changes now but could cause changes.

o Kinetic Energy (energy of motion) – energy due to motion.

Energy of Position Potential Energy is energy that in not causing any changes now, but could cause changes in the future. 2 Types of Potential Energy o Gravitational Potential Energy - is the amount of energy

an object has based on its weight and height. o Elastic potential energy - is the amount of energy an

object has based on being bent or stretched.

Energy can come in many different forms but there are six basic forms of energy: 1. mechanical energy 2. electrical energy 3. heat energy 4. light energy 5. sound energy 6. chemical energy

Mechanical energy

is the energy that an object has due to its motion or its position.

Potential (energy of position) – energy not causing any changes but could cause changes.Kinetic (energy of motion) – energy due to motion.

Electrical Energy

Electrical energy comes from the movement of charged particles, such as electrons.

Electrical energy is also referred to as electricity. Machines can change electricity into many other forms of

energy like heat, light, sound, or mechanical energy. Electricity travels through conducting materials, such as

wires. Electrical energy can be changed into other kinds of

energy.

Heat Energy

Heat or thermal energy is how hot or cold an object is.

Heat energy is transferred from warmer objects to colder objects.

Heat energy can be produced from other forms of energy.

The temperature of an object is related to how much thermal energy that an object has.

Light EnergyLight energy is a type of wave energy which can be sensed by the eyes.

Other types of energy can produce light energy. Light energy produced by the Sun is called solar energy. Light energy always travels away from its source.

Light Energy

Light travels away from its source in a straight line until it strikes an object or travels from one medium to another.

Things that give off light often also give off heat.

Light can: Reflect – the bouncing back of light from a

surface. Refract – the bending of light as it moves through

one material. Absorb – when light is absorbed by an object.

Chemical Energy

Chemical energy is the energy found in a substance due to the arrangement of its particles.

Chemical Energy is a type of potential energy or stored energy.

Chemical energy is present in several situations of energy transfer.

Sound EnergySound energy is the energy of sound waves as they travel. Sound is created by the vibration of an object. The speed of a sound wave depends on what the wave is traveling through.

Sound travels more quickly through a solid than through a liquid or through air.

Sound waves cannot travel through a vacuum such as outer space because there is nothing there for the waves to travel through.

Sound energy can be produced by other forms of energy.

PitchFactors that Affect Pitch Speed of the Vibrations Tightness (or tension) Size, such as the length or

thickness of a string, can affect pitch.

2. Jose can throw a baseball from the outfield all the way back to home plate. Why does he have to move his arm in order to make the ball fly all that way?

A. He has to get the ball high enough in the air so the air can support it.

B. The ball's energy can only be released if he lets it go above the ground.

C. Moving his arm makes the ball's own energy take it in the right direction.

D. He has to transfer some of his muscle's energy to the ball to make it move.
