K or P?
Types of Energy
Definitions
100
Burning a candle. (2 steps)
Chemical energy -> heat energy + light energy
100

A young boy begins riding his bicycle down a hill.

potential energy ---> kinetic energy

100
What is the process of saving up or storing energy?
Potential energy.
100
Energy that has the ability to fall; this type of energy increases the higher up you go.
Potential (gravitational) energy.
100
Energy is defined as _________.
The ability to do cause change or do work!
200
Using a hot plate to boil water. (2 steps)
Electrical energy -> heat energy
200

A firecracker explodes in the sky

chemical energy ----> light + heat + sound energy

200
What is energy in motion.
Kinetic energy.
200
"You can burn it or you can eat it."
Chemical energy.
200

The process of changing energy from one form to another.

Energy conversion

300
A hungry football player eating a large sandwich to use the food for energy. (2 steps)
Chemical energy -> mechanical energy
300
Explain the energy transformation when a television is turned on.
Electrical Energy =====> Light and Sound Energy
300
A heavy vase on a table has this type of energy.
(Gravitational) potential energy.
300

This type of energy cannot travel through empty space. It must have a medium to travel through. Caused by vibrations.

Sound energy.

300

A resource that cannot be readily replaced by natural means at a quick enough pace to keep up with consumption.

non-renewable resource

400

A tree growing into an apple tree

electromagnetic energy -> chemical energy

400
As the mass of an object moving at a given speed decreases (ie-50 mph to 25 mphs) its kinetic energy will ______
Decrease
400
A person running down the sidewalk has this type of energy.
(Mechanical) kinetic energy.
400

The energy of moving particles. The faster the particles move, the warmer they get.

Thermal energy

400

Explain the law of conservation of energy!

Energy cannot be created or destroyed, it can only change forms!

500
