Forms of Energy
This is the capacity to produce changes... It allows changes in matter to take place.
What is energy?
Resources that we use to produce electricity.
What are energy sources.
The electricity that flows through wires and electrical devices.
What is electric current?
This effect can occur in a bulb or torch
What is a light effect?
These sources are used faster than they replenish. They eventually run out and pollute the environment.
What is nonrenewable energy?
What is light energy?
Sources that quickly replenish and do not pollute.
What are renewable energy sources?
Electricity passes through these materials easily. (metal, copper)
What are conductors
It turns a circuit on or off.
What is a switch.
They are coal, natural gas, and petroleum. They produce large amounts of carbon that pollute the atmosphere.
What are fossil fuels?
Food, fuels, cells, and batteries store this kind of energy.
What is chemical energy?
This source uses mechanical energy called hydroelectric energy.
What is water?
These materials do not allow electricity to pass through them.
What are insulators?
This effect can rotate a motor, like in a blender.
This conducts the current and is usually made of copper.
What is a wire?
This kind of energy is inside all bodies. It is measured by temperature.
Contained in the interior of the Earth, we use this energy to produce electricity or heat water.
What is geothermal energy?
Transforms electrical energy into light, sound, or movement.
What is the output device?
This provides electrical energy; it can be a cell or a battery.
What is a generator.
When energy is produced and used in a way that causes the minimum negative impacts.
What is sustainable energy?
Substances such as uranium and plutonium contain this kind of energy.
What is nuclear energy?
The remains of living things containing chemical energy; this is used to produce electricity or as fuel for cars.
What is biomass?
A closed path around which electricity can flow. It is made up of several components and connected by wires.
What is an electric circuit?
Mechanical energy comes from...
What is wind, flowing water, and steam.
They are uranium and plutonium; they have a large amount of energy and the waste has to be stored in high-security facilities.
What are nuclear fuels?
