What is chemical energy
What is energy stored in bonds between molecules. When the bonds are made of broken, energy is stored or released. An example of this is photosynthesis.
100
What is solar energy?
What is energy that comes from the sun
100
What does chemical energy convert to?
What is chemical energy in the gas converts to mechanical energy to make the car move and the thermal energy that is produced through the exhaust pipe.
100
heat energy transfers when electromagnetic waves (visible light) interact with particles increasing their kinetic energy.
What is radiation
100
What is the original energy stored in coal, oil, and natural gas
What is fossil fuel
200
What is electrical energy?
What is energy produced when electrons flow through materials or jump from one place to another. Lightning is an example of this.
200
What is sound energy?
What is vibrations that move through solids, liquids and gases
200
How is heat energy produced in a car?
What is some of the energy is also converted into heat energy from friction between the tires on the road.
200
How does a candle demonstrate conduction? How does a candle demonstrate convection?
What is a candle demonstrates conduction when the cool particles of the wax meet the hot particles of the flame and melts the wax. A candle demonstrates convection when heat is given off from the flame and that heat rises.
200
What forms of energy require a medium through which to travel?
What is sound
300
What is heat energy?
What is the average kinetic energy of particles; example is boiling water
300
What is electrical and heat energy?
What is energy that is transported through metal wire
300
heat energy that transfers when particles with greater kinetic energy collide with less energetic particles Example: a metal fork held over a candle flame with heat up first at one end, while the other end of the fork remains cool. Eventually, the molecules will move to the cool end of the fork and become hot
What is conduction
300
What kind of energy is used when people speak?
What is sound energy and the medium is air
300
A purple object absorb all colors of light except for...
What is purple
400
What is mechanical energy?
What is energy that consists of kinetic and gravitational potential energy
400
What does wind energy turn into? What does solar energy turn into?
What is wind energy = electrical energy; solar energy = wind energy
400
energy that arises from an object's motion
What is kinetic energy
400
occurs when light travels at different speeds through different substances. Example: when you put a pencil in a glass of water it appears to be bent.
What is refraction
400
When you go outside on a sunny day, you might feel heat from the sun on your skin. What type of solar energy is this?
What is infrared radiation
500
What is nuclear energy?
What is energy within the nucleus of an atom.
500
a repeating vibration that travels through space and time
What is wave
500
motion of a heated material due to gravity and differences in density; currents in the earth's mantle produce forces that move tectonic plates
What is convection
500
Is solar energy and natural gas renewable or nonrenewable?
What is solar energy = renewable; natural gas = nonrenewable

A pole vaulter runs with the pole, plants it in the ground, rises up in the air, and soars over the bar. Which of the following statements is not true about the energy transformations?
What is the place where the pole vaulter has the least potential energy is at the top of his vault
