Energy Transformations
Provide an example of CHEMICAL ENERGY -> HEAT ENERGY + LIGHT ENERGY
Burning a candle...
energy that an electric current carries
electrical energy
What is the process of saving up or storing energy?
Potential energy.
Energy that has the ability to fall; this type of energy increases the higher up you go.
Gravitational energy.
Energy is defined as _________.
the ability to cause change
Using a hot plate to boil water is an example of ______ energy turning to _______ energy.
Electrical energy -> heat energy
the sum of kinetic energy and potential energy of the particles that make up an object and produce heat
thermal energy
What is the process of spending energy or energy in motion?
Kinetic energy.
a force that resists the sliding of two surfaces that are touching
friction

chemical>electrical>radiant> thermal
the energy that electromagnetic waves carry
radiant energy
the sum of potential energy and kinetic energy in a system of objects
Mechanical energy.
the energy that sound carries
sound energy
Using a solar-powered calculator involves transforming _________ energy from the sun to _____________ energy
Radiant energy -> electrical energy
stored when an object is compressed or stretched
elastic potential energy
When energy is transferred in a system, the total amount of energy before the transfer is _____________ after the transformation is complete, just in different forms.
a. different
b. the same
c. lost
d. transformed into light
The same
the transfer of energy that occurs when a force makes an object move in the direction of the force while the force is acting on the object
Work
A solar panel on the roof of a building is used to power the building . what energy transformation has occurred
Radiant energy -> electrical energy
energy stored and released in the nucleus of an atom
nuclear energy
A person that has just jumped from an airplane has this type of energy.
(Gravitational) potential and kinetic energy.
The Sun contains many types of energy. Name at least 2 types.
Heat, Radiant, Nuclear and Gravitational
List the Law of Conservation of Energy.
Energy can be not be created or destroyed only transferred
