Types of Energy
Definitions
100

Burning a candle. (2 steps)

Chemical energy -> heat energy + light energy

100
A young boy rides his bicycle down the sidewalk
chemical energy ---> mechanical 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 energy
200
What is energy in motion.
Kinetic energy.
200
"You can burn it or you can eat it."
Chemical energy.
200

the push or pull of an object

force

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 is generated by a force - a push or a pull. Object is moving due to the force.
Mechanical energy.
300

the distance an object travels per unit of time

Speed

400
Using a solar-powered calculator. (3 steps)
solar energy -> electrical energy ->light 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.
Heat (thermal) energy
400
Explain the law of conservation of energy!
Energy cannot be created or destroyed, it can only change forms!
500
A solar panel on the roof of a building used to heat and cool the building. (2 steps)
solar energy -> electrical energy
500
Explain the transformation that takes place when you turn a flashlight on. (3 steps)
Chemical (battery)-->Electrical (flow of electrons) --->radiant or thermal (light)
500
A person that has just jumped from an airplane has this type of energy. Explain!
potential and kinetic energy.
500
