Energy changing from one form to another...

is sometimes called energy conversion or energy transformation.

>>> Any form of energy can change into any other form of energy.

Multiple Choice

See the picture. There is electrical energy coming from the outlet in the wall. When the energy goes into the lamp what energy does it transform into?

• Mechanical Energy

• Thermal Energy

• Sound Energy

• Light Energy

Often one form of energy can change into more than one form.

Chemical-> Heat-> Kinetic-> Electrical-> Heat

Multiple Choice

Skateboarder #1 is showing potential energy as he waits at the top of the half pipe.

Skateboarder #2 has dropped into the half pipe, to what type of energy has he converted his potential energy?

• Potential

• Thermal

• Kinetic

• Chemical

Food is chemical energy used to make the body function.

• It is converted into kinetic energy to help the body move

• It is also converted into thermal energy to keep the body warm.

Energy Conversion in Plants

• Chemical energy stored in the food we eat ultimately comes from the sun.

• The process is called photosynthesis. Light energy is converted into chemical energy.

Chemical Energy

The movement of electrical charges usually through wires​

Electrical Energy​

​

The energy of the movement of particles in an object. ​

Thermal Energy

The total potential and kinetic energy. ​

Mechanical Energy

The transfer or movement of heat without matter to carry it

Radiant Energy​

​

Vibrations that can be heard.​

Sound Energy

​

​The energy in the nucleus, or core, of an atom.

Nuclear Energy

​

Stored Energy because of an object's position or condition.

Potential Energy

The energy of Motion.

When energy is being used. ​

Kinetic Energy

​Energy Transformations: Kinetic and Potential

Multiple Choice

Whenever work is done, energy is transformed or transferred to another system.

• Energy is the ability to do work.​

Energy and Work

Types of Energy

​Mechanical	​Potential	Kinetic
Chemical	Thermal	Nuclear
Electrical	​Electromagnetic	Sound

​Each of these forms of energy can be converted into other forms of energy.

definition: the energy associated with the motion or position of an object.

• this is the sum (total amount) of potential and kinetic energy in a system.

  • Kinetic energy: the energy of motion

  • Potential Energy: the energy that is stored in an object (energy of position)

Mechanical Energy

definition: energy that results from the flow of electrons

• electric charges can exert forces that do work​

Electrical Energy

definition: the energy stored in chemical bonds

• when bonds are broken the released energy can do work​

Chemical Energy

definition: energy given off as heat (friction)

• Force vs Friction

  • Friction is a type of force that opposes motion, or makes it difficult for an object to move across a surface.​

​

Thermal Energy

definition: the energy stored in atomic nuclei

• Remember:

  • nuclear fission releases energy by splitting nuclei apart

  • nuclear fusion combines 2 nuclei into a larger nucleus​ which releases energy

Nuclear Energy

definition: energy that moves through a substance such as air or water

• this is caused by vibrations (periodic back-and-forth motion).

• Solids, liquids and gases can transmit sounds as waves.

​

Sound Energy

definition: energy that travels through space in the form of waves (also called radiant energy)

• visible light and x-rays are examples of electromagnetic energy​

Electromagnetic Energy

The process of changing energy from one form to another

Energy​

States that energy cannot be created nor destroyed, it can only be changed (transferred).

• energy can be transferred to another object/system or into another form

  • example:

    • a roller coaster

      • at the top of the coaster you have potential energy but when you drop it turns to kinetic energy

Law of Conservation of Energy
