Potential Energy:
• Energy is measured when it is
transferred from one form to another
or from one object to another.
• Energy = capacity to do work.
• Work = amount of energy transferred.
• Energy and work = scalars.
• Measured in J.
• Stored energy = potential energy.
• Movement energy = kinetic energy.
Kinetic Energy:

Gravitational Fields:
• All masses attract each other - all masses have a

• Kinetic energy (Ek) = energy of an object
when it moves.

• Weight on Earth = gravitational force pulling Gravitational
downwards towards the Earth's centre.
Potential Energy:
• Greater mass = greater weight.
• Earth’s gravitational field strength (g) = 9,8 N.kg-1. • Gravitational potential energy = stored

reference point.
• Gravitational potential energy (Ep) is
transferred to an object when it is lifted
above the reference point against the
vertical force of gravity.
• Ep is transferred from an object when it
is moved below the reference point.
• Ep = mgh.
