PRESENTATION OUTLINE

energy transformation

the process of changing energy from one of its forms into another

ENERGY THAT COMES FROM HEAT, GENERATED BY THE MOVEMENT OF TINY PARTICLES

nuclear energy

energy released during nuclear fission or fusion, especially when used to generate electricity.

energy

Energy is the ability to do work

conduction

the transfer of heat or electricity through a substance and between two regions

convection

the tendency of hotter and therefore less dense material to rise

radiation

energy radiated or transmitted in the form of rays, waves, or particles.

thermal expansion

matter to change its shape, area, and volume in response to a change in temperature

Joules

unit of work or energy, equal to the work done by a force of one newton

Law of Conservation of Energy

energy can neither be created nor destroyed; rather, it can only be transformed

gravitational potential energy

energy an object possesses because of its position in a gravitational field

heat transfer

can occur either by conduction, convection or radiation
