KINETIC AND POTENTIAL ENERGY WORKSHEET Name:________________________
Potential energy (PE) = mgh
Kinetic energy (KE) = 1/2 m v2
Total mechanical energy = PE + KE
Take notes from Power Point:
Potential energy sample question: A block is sitting on a platform 20 m high. It weighs 50 kg. How much
Potential energy does it contain?
Kinetic energy sample question: You serve a volleyball with a mass of .05 kg. The ball leaves your hand with
a speed of 30 m/s.
Total mechanical energy sample question: What is the Mechanical energy when
the pendulum is at the high point (height=2 m)?
Kinetic energy sample question: What is the kinetic energy when the pendulum is at the halfway point
(height=1 m) when the total mechanical energy is 4 J (from previous question)?
Directions: Write down the definition for each from your Cornell notes
