FORMS OF ENERGY
This type of energy is the internal energy of an object due to the motion of its particles, and increases as a substance gets warmer.
What is thermal energy?
This is the flow of electric charge through a conductor.
What is electric current?
This is what we cannot do to energy, even though we can change it from one form to another.
What is making energy?
This is the term for something found in nature that is valuable to humans, like air, water, or minerals.
What is a natural resource?
This is the term for a material that slows or stops the flow of energy, such as electricity or sound.
What is an insulator?
This type of energy is produced by vibrations of material.
What is sound energy?
This is a material through which electricity flows easily.
What is a conductor?
This is what happens to the chemical energy stored in food when we eat it.
What is changing into energy of movement (kinetic energy)?
This is the term for a natural resource that cannot be replaced easily.
What is a nonrenewable resource?
This device can open or close the path in a circuit, allowing or stopping current flow.
What is a switch?
This type of energy can travel through space.
What is light energy?
This device increases the number of charged particles flowing in a circuit.
What is a voltage source?
This is what a microwave oven turns electrical energy into.
What is thermal energy?
This is the most plentiful fossil fuel, found between layers of rock and used mainly to generate electricity.
What is coal?
This type of circuit has only one conductive path, where resistance increases with each resistor added.
What is a series circuit?
This type of stored energy is released when a reaction splits the particles that make up matter.
What is nuclear energy?
This object in a circuit resists the flow of energy and transforms it into motion, light, or heat.
What is a resistor?
This is the type of energy stored in a wind-up toy's spring before it is released.
What is potential energy?
This thick, black substance is also called petroleum and can be turned into gasoline.
What is crude oil (oil)?
This is a path with little or no resistance connecting two ends of an electrical source, which can cause currents large enough to damage appliances or start fires.
What is a short circuit?
Because burning wood and digesting food both involve breaking and forming links between particles to release stored energy, both processes are examples of this same form of energy.
What is chemical energy?
Because the wiring in your home uses this type of circuit, your microwave keeps working even if a lightbulb elsewhere in the house burns out.
What is a parallel circuit?
Starting with the chemical energy stored in coal and ending with electricity flowing through power lines, this is the total number of energy transformations that take place in a coal power plant.
What is three?
Unlike coal and oil, this nonrenewable resource does not come from the remains of once-living things, and it isn't burned, but instead goes through a nuclear reaction to release energy.
What is uranium?
If the switch in a flashlight is left in the open position, this is what happens to the electric current, even though the battery still holds plenty of stored chemical energy.
What is no current flows (the circuit is broken)?
