Energy and Forms of Energy, Energy Transformation

potential energy

stored energy that results from the position or shape of an object

the energy that an object has because of the position, shape, or condition of the object

kinetic energy

the energy of motion

work

the transfer of energy that occurs when a force is applied over a distance

elastic potential energy

the energy of stretched or compressed objects

gravitational potential energy

Potential energy that depends on the height of an object

mechanical energy

The energy associated with the motion and position of everyday objects. Formula is potential energy + kinetic energy.

thermal energy

The total energy of motion in the particles of a substance

electrical energy

Energy caused by the movement of electrons.

The energy of electric charges

chemical energy

Potential energy stored in chemical bonds

nuclear energy

Energy stored in the nucleus of an atom

electromagnetic energy

A form of energy that travels through space as waves.

The energy of light and other forms of radiation.

sound energy

Energy caused by an object's vibrations.

Energy of vibrations carried by air, water, or other matter.

example of mechanical energy

A football thrown by a quarterback, riding a bicycle, or kicking a soccer ball.

example of thermal energy

ice cream melting on a hot day, hot springs, campfire, or cup of hot tea.

example of electrical energy

a shock from a metal doorknob, lightning, batteries in use, or static

example of chemical energy

energy stored in a match, gasoline, foods you eat, or cells in your body.

example of nuclear energy

nuclear fusion in sun, nuclear power plants use fission

examples of electromagnetic

The sunlight, microwaves, and x-rays.

examples of sound energy

clapping, snapping fingers, singing, or anyone's voice.

energy

the ability to do work or cause change

When you stretch a rubber band, you give it

elastic potential energy

According to the _____________________________________________________, energy can not be destroyed or created.

law of conservation of energy

energy transformation (steam iron)

electric energy to thermal energy

energy transformation (sun to plants)

electromagnetic energy to chemical energy

Joules

SI unit for energy

energy transformation (wood burning)

chemical energy to thermal & radiant energy

two types of potential energy

gravitational and elastic

Most common energy transformations is between

kinetic and potential energy

forms of energy

electric, mechanical, nuclear, thermal, electromagnetic, sound, and chemical

energy transformation (sun to plants to animal eating plants and running)

electromagnetic to chemical to mechanical

energy transformation

a change from one form of energy to another

matter

anything that has mass and takes up space (volume)

In waterfalls such as Niagra Falls,

potential energy is transformed to kinetic energy.

When potential energy increases,

kinetic energy decreases.

When kinetic energy increases,

potential energy decreases.

solar to light and heat energy

mechanical to sound

Law of Conservation of Energy

Energy can't be created or destroyed, only changed
