# Energy

## 19 terms

### Kinetic Energy

anything that has movement or motion
motion of waves, electrons

### Motion (+example)

energy of the moving object from one place to another
displacement energy

example: wind

### Thermal (+example)

internal energy in a substance
vibrating and movement of atoms and molecules within an object or substance

example: geothermal

### Electrical (+example)

energy found in the movement of electrons

example: lightning and electricity

### Sound(+example)

movement of energy through objects or substances in vibrating, long individual waves
(compression and rarefaction)

example: music

energy found in the electromagnetic spectrum and travels in transverse waves

example: the sun, solar energy

### Potential Energy

the energy something has that is about to start ir move (energy of position)
*stored energy

### Chemical (+example)

energy stored in the bonds of atoms and molecules
'food' 'fuel' energy

example: biomass, petroleum, natural gas, propane, and coal

### Stored Mechanical (+example)

energy stored in objects or substances by the application of force

example: spring, elastic, wheels

### Nuclear (+example)

energy stored in the nucleus of the atom. its the energy that holds the nucleus together

*found in the bonds that holds the nucleus particles together

example: the nucleus of a uranium atom

### Gravitational potential (+example)

energy of position or place

example: hydropower dam

### Joules

the unit for energy and work

### Newton Meters

1 Newton meter= 1 Joule

### Law of Conservation of Energy

the law that states that energy cannot be created or destroyed but can be changed from one form to another

### How does energy flow?

It flows from hotter to cooler objects

w=F x d

### Renewable Energy

their supplies are replenishable in a short time

### Nonrenewable Energy

cannot be replenished in a short period of time

### Where does kinetic and potential energy transform back and forth into each other? (in roller coasters and pendulum)

Kinetic increases as the ball goes down and decreases as it goes up (speed goes up, kinetic increases)
