UNIT 12 ENERGY

What are the two main types of energy?

• Potential energy and chemical energy

• Kinetic energy and chemical energy

• Potential energy and kinetic energy

This energy causes temperatures to rise

• heat energy

• chemical energy

• kinetic energy

This energy is expressed through activity or movement

• heat energy

• chemical energy

• kinetic energy

• Potential energy

This energy is stored, ready to be released

• heat energy

• chemical energy

• kinetic energy

• Potential energy

This energy is released by a chemical reaction

• heat energy

• chemical energy

• kinetic energy

• Potential energy

It is the action or movement produced by kinetic energy

• work

• conservation of energy

• friction

• release

• transfer

A force that causes resistance when surfaces rub against each other

(rub= frotar)

• work

• conservation of energy

• friction

• release

• transfer

It means "liberar" in spanish

• work

• conservation of energy

• friction

• release

• transfer
