you need to determine if the object has KE or GPE or both. Then find their values. Be sure to include the correct units

 

A 2-kg bowling ball sits on top of a building that is 40 meters tall.

Circle one: KE / GPE / both

Show your work for finding the values of each type of energy the object has:

The ball is sitting....not moving...so it has no KINETIC energy...it has  POTENTIAL energy

 

GPE =    mgh =  2 kg  9.81 m/sec^2  40 m = 784.8  kg-m^2/sec^2 = 784.8 N-m = 748.8 j

So that means if the ball rolls it has kinetic energy?

Yes    Kinetic   means 'moving' energy
