Energy Test

How does heat energy reach the Earth from the Sun

• Convection

• Radiation

• Conduction

• Insulation

An object at rest will stay at rest until

• I move it

• It will always stay at rest

• Energy will move

• an outside force acts on it

What is the definition of CONDUCTION?

• When heat is transferred from objects like rays of light or electromagnetically.
• a  hot liquid or air that  expands, becomes less dense, and rises or becomes more dense, and sinks.
• When heat transfers from objects that are touching.
• When heat transfers through the heater or AC in your house.

The transfer of heat by currents through liquids of gases is called

• Perspiration
• Radiation
• Conduction
• Convection

The transfer of energy by waves or particles is called

• conduction

• convection

• radiation

• insulation

Energy due to motion is called ______________ energy.

• kinetic

• mechanical

• potential

A ball sitting on the edge of a table has potential energy, because it is not moving.

• true

• false

Energy stored in objects that are stretched or compressed is _________________.

• elastic potential energy

• gravitational potential energy

• kinetic potential energy

What kind of energy does a tool hung on the wall in a garage have?

• gravitational potential energy

• kinetic energy

• gravitational kinetic energy

What does the Law of Conservation of Energy say? 

• Matter of an object is affected by force.

• Matter is neither created or destroyed.

• For every action, there is an equal and opposite reaction.
