2. Energy is the ability to do work
Work is done when a force moves an
object over a distance in the
direction of the force
W = F x d (Force x Distance)
Measured in Joules (j)
4. The Energy of Position;
The energy an object has because of
its position. The ability to have
energy or stored energy
Examples:
The wound spring in a wind-up toy
The stretched bow of a bow and
arrow
5. Energy of Motion
◦ All moving objects even protons,
neutrons and electrons have it.
◦ The greater the mass of the moving
object, the greater the Kinetic Energy
Examples:
◦ The swinging of a hammer.
◦ A ball rolling down a hill
