This cannot be replaced or is replaced much more slowly than it is used.
What is a nonrenewable resource?
In this system a group of objects transfer energy only to each other.
What is a closed system?
This energy source stores potential energy in the bonds between atoms.
What is chemical energy?
This is a renewable resource and does not produce air pollution.
What is water?
This energy resource is nonrenewable, produces smog, releases substances that can cause acid precipitation and can create a risk of oil spills.
What is fossil fuels?
Energy resources that formed from the buried remains of plants and animals that lived millions of years ago.
What are fossil fuels?
This is a force that opposes motion between two surfaces that are touching.
What is friction?
Thermal energy is kinetic due to the motion of this.
What are moving particles?
This resource is almost a limitless source of energy, and the power plants require little land.
What is Geothermal energy resource?
This energy resource is only practical in windy areas.
What is wind?
Fossil fuels derive their energy from this source.
What is the sun?
The release of this energy form during every energy conversion is the reason there will never be a perpetual motion machine.
What is thermal energy?
This potential energy is stored in the nucleus of an atom.
What is nuclear energy?
This energy resource is renewable and inexpensive.
What is Biomass?
This energy resource requires large areas of farmland and produces smoke.
What is biomass?
This is how long it takes for fossil fuels to form.
What is million of years?
What is energy efficiency?
This form of kinetic energy is due to the vibrations of electrically charged particles.
What is radiant/light energy?
This energy resource is a very concentrated form of energy and does not produce air pollution.
What is nuclear energy resource?
This energy resource produces radioactive waste and is nonrenewable.
What is nuclear?
Fossil fuels can be found here.
What is buried underneath the Earth's surface?
This can cause a car to be more energy efficient.
What is aerodynamics?
This form of energy is the result of moving electrons. It can also be kinetic or potential energy.
What is electrical energy?
This energy resource is renewable, relatively inexpensive to generate and does not produce air pollution.
What is wind?
This energy resource is expensive to use for large-scale energy production, and it is practical only in sunny areas.
What is solar energy resource?
