Science Unit 3 forms of energy

Kinetic energy is also known as energy

in motion or in use

Potential energy is also known as energy

that is stored or not in use.

What is the Law of Conservation of Energy?

It says that Energy cannot be created or destroyed and that energy only changes form.

The KE and PE added always equal

100%

What would happen to KE if there was no air resistance

It would equal 0

What is energy

the ability to cause motion or change

All matter has what

Energy

What does energy explain?

Complex interactions in ecosystems, hurricanes, and simple events

What is energy related to?

Forces

What determines PE

How high up it is/ where it is.

All moving objects and particles have

KE

KE amount determined by

Speed

a system is made of

components, inputs and outputs and processes

Components interact in

processes that cause change in the form of Energy

What are inputs and outputs

energy that enter and leave the system

When can an objects energy be transferred into another object?

WHen they exert forces on each other

What can energy be transformed into?

Friction, air resistance, and can create heat and sound

which energy is motion of objects (legs, balls thrown, gears in a motor)

Mechanical Energy

which energy is stretchy materials ( springs, rubber bands, bouncy balls)

Elastic energy

which energy is position off the ground (dropping stuff)

Gravitational Energy

which energy is charged electrons

Electrical energy

which energy is charged poles (electromagnetic motors, generators)

Magnetic energy

which energy is radiation, light energy (No matter involved, microwaves, IR, UV)

Electromagnetic energy

which energy is heat, vibration of atoms ( When radiation energy contacts an object, friction, air resistance)

Thermal energy

which energy is molecules changing ( food, batteries, fossil fuels, photosynthesis)

Chemical energy

which energy is vibration of atoms

Sound energy

which energy is nucleus of atoms

Nuclear energy

The Electromagnetic spectrum goes from

biggest to smallest frequency.

Greater the velocity-

greater KE

greater the mass-

greater the KE and PE

Greater the height-

Greater the PE
