• I CAN determine the differences and
similarities between potential and
• I CAN use different measurements to
find both potential and kinetic energy.
• I CAN use given measurements to find
both potential and kinetic energy.
• I CAN relate these equations to realworld situations (Would you rather).
What is energy?
Energy: how much work something can
measured in Joules, J
-Energy can change forms
• Energy is always conserved so it must
be changed from one form to
Potential the stored energy from the
position of an object
• Potential Energy = mgh or wh
• m = kg g = 9.8 m/s2 h = Height (meters)
• Kinetic energy of a moving object
due to its motion
