What is work?

• Energy expended when an objects speed is increased or moves against an opposing force

• A job that you have to go after Highschool

• The rate of which power is done

• (W) watts

What are two things that have to happen for work to be done?

• Potential energy

  &

  elements position

• Property of an object

  &

  A system that enables it to do work

• Application of a force

  &

  Movement of something by that force

• Energy

  &

  Conductors

What is gravitational potential energy

• The energy stored in an object due to mass

• Energy stored and held in readiness by an object virtue of its position

• Energy due to the position or movement of an object

What is an electric field?

• Negative and positive atoms that go in an orbit to protect.

• Something that goes in an orbit at the speed of light.

• Something that moves through a circuit at the speed of light.

• The flow of electricity in an electronic circuit. As well as the amount.

What is the potential difference?
