P: Vocabulary Notes

Law of conservation of energy

Energy cannot be created or destroyed but can be transferred from one form to another.

Thermal Energy Thermal (heat) energy: The

internal energy of a substance due to the movement or vibration of its atoms or molecules. (heat)

Transfer of Energy

Energy transfer is the transfer of energy from one object or material to another.

Investigate is a body of techniques for

investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.

Conduction The transfer of energy by

direct contact.

Convection The transfer of energy

through fluids.

Radiation The transfer of energy through

empty space.
