energy guides notes

energy that has the potential to become another form of energy
EX. ball stopped, students sitting still, sitting at the top of a rollercoaster

Potential Energy (PE)

the form of energy that it possesses due to its motion
EX. ball moving, students running, going down a roller coaster

Kinetic Energy (KE)

Energy Basics

Similar to how a heavier object will need more force to move, if an object is larger it will have more energy than a smaller object.
Therefore, the larger the object = the more energy it has
For example, a moving airplane will have more kinetic energy than a person on a bicycle even if they were going the same speed

Radiant Energy

Definition: energy transmitted in the forms of waves through space or a medium
EX. Sun, microwave, charcoal grill, natural gas

Examples :

Microwaves

Gas flames

Chemical Energy

Examples:

Chemical energy- is energy stored in the bonds of
atoms and molecules. Chemical energy is converted to
thermal energy when people burn wood in a fireplace or
burn gasoline in a car's engine.

Electrical Energy

Electric Energy- is the energy
that an electric current carries.

Examples:

Sound Energy

Sound energy- is the movement of energy in waves. It is
generated by vibrations and needs a medium, such as air,
water, or a solid to travel through.It is produced when
sound waves move outwards from a vibrating object or
sound source.

Travels in waves by a straight line through space through space, the only form of energy we can see
Ex. Sunlight, fire, flashlight, stars

Thermal Energy

Thermal Energy: is the energy due to the motion of
particles that make up an object. Thermal energy
moves from hot or warm objects and heats up the
contacting surface.

Examples:

Mechanical energy = Kinetic energy + Potential energy​

Renewable natural sources of energy that nature replaces rapidly
They will be replenished, renewed or will come back

​

Renewable Energy

Nonrenewable sources of energy are limited in numbers because it takes a long time to replenish them or make new.
These sources do cause pollution.
