Potential energy is energy that is stored in a system. Kinetic energy is energy of motion. Energy
can be transformed from potential energy to kinetic energy, or vice versa.
Energy is a quantity that
can be measured. The joule is the unit used to measure energy, represented by J.
Potential energy (PE) = 9.8 (m/s2) x mass (kg) x height (m)
(where 9.8 is the acceleration due to gravity)
Kinetic energy (KE) = 0.5 x mass (kg) x speed? (m/s)
Delany is getting ready to race her soapbox car down a hill. The car weighs 60 kg. Delany
weighs 35 kg. The height of the hill is 3.5 meters. Write and solve the equation for the
potential energy of the car, with Delaney in it, before sliding down the hill.
