Vocabulary
The ability to create change in a system.
What is, energy?
The measure of the average speed of atoms in a sample.
What is, temperature?
Earth's ultimate source of energy and the source of most of earth's surface heat.
What is, the Sun?
The formula for density.
What is, D=M/V or D=Mass/Volume?
The transfer of heat through the motion of liquids and gases.
What is, convection?
What is, potential energy?
Atoms in a hot object have an average temperature that is...
What is, fast?
Also know as kinetic energy, this energy is created by the constant motion of atoms.
What is, motion energy?
This is an example of a gas floating in a gas.
What is, a balloon?
The transfer of heat by direct contact of atoms and molecules.
What is, conduction?
A form of energy caused by the continuous motion of atoms.
A teacup that is filled with 100 degree Celsius water has more/less heat energy than a bucket filled with 50 degree Celsius water.
What is, less?
This is created when two objects rub together. The more there is, the more energy is built up.
What is, friction?
The result when a solid object has a force of 10.6 newtons and it is placed in a bucket of fluid with an upward force of 10.8 newton forces.
What is, it floats?
An upward lifting force that acts on an object when it pushes aside a fluid.
What is, buoyant force?
Heat transfer that involves energy waves and no direct contact or movement by atoms.
What is, radiation?
Hawks and other birds use this type of energy transfer to fly.
What is, convection?
A lamp giving off light and heat is an example of...
What is, energy flow and heat loss?
The amount of matter in an object.
What is, mass?
Matter that can flow, usually a liquid or a gas.
What is, a fluid?
The mass of an object divided by its volume.
What is, density?
When you place a cold spoon in a hot cup of cocoa conduction occurs when the heat flows from...
What is, the hot cocoa to the cold spoon?
At the top of a roller coaster you have more ( ) energy and less ( ) energy.
What is, potential energy and kinetic energy?
The method used to measure the volume of an odd-shaped object.
What is, the displacement method?
Matter is made up of tiny particles.
What are, atoms?
