Forms of Energy
The ability to do work.
Energy
A force that resists the motion of two touching surfaces.
Friction
These are the remains of ancient organisms that can be burned as an energy resource.
Fossil fuels
The ability to cause change.
Energy
The energy that an electric current carries.
Electrical energy
Energy due to motion.
Kinetic energy
You use a lamp to change electrical energy into _______ energy.
Radiant
This type of energy resource takes advantage of pools of hot water beneath the Earth's surface.
Geothermal energy
Energy stored in objects that are compressed or stretched, such as springs and rubber bands.
Elastic potential energy
Energy that is stored in the nucleus of an atom.
Nuclear energy
Give a specific example of potential energy.
Gravitational, elastic, or chemical
Which type of energy is the "waste energy" generated when energy is used?
thermal energy
Name a renewable energy source that is most likely to produce pollutants when used.
Biomass
An energy resource that is replaced as fast as, or faster than, it is used.
Renewable energy resource
An energy resource that is available in limited amounts or that is used faster than it is replaced in nature.
Nonrenewable energy resource
Atoms are split in this resource to create nuclear energy.
Uranium
Food is considered _________ that we transform to kinetic energy which is necessary for movement.
Chemical potential energy
Name 4 renewable energy resources.
Biomass, wind, solar, geothermal, hydroelectric
Stored energy due to the interactions between objects or particles.
Potential energy
An energy resource that cannot be used up. Give one example.
Inexhaustible energy resource. Wind or solar
Which type of energy is from the Sun, microwaves, and light?
Radiant
Describe where the kinetic and potential energies are at their maximum when throwing a ball up into the air.
Kinetic is highest when it first leaves your hand or when it lands back in your hand and potential is highest at the top of the arch.
Describe where geothermal energy comes from.
Geothermal energy comes from the decay of radioactive nuclei deep inside Earth which can produce pockets of hot water and steam. Sometimes wells can be drilled to these reservoirs so they can be utilized to produce energy.
The total energy of an object or groups of objects due to large scale motions and interactions.
Mechanical energy
What is the law of conservation of energy?
Energy can be transformed from one form into another or transferred from one region to another, but energy cannot be created or destroyed
