The Work-Energy Relationship
... Answer: The only force doing work is gravity. Since it is an internal or conservative force, the total mechanical energy is conserved. Thus, the 100 J of original mechanical energy is present at each position. So the KE for A is 50 J. The PE at the same stairstep is 50 J (C) and thus the KE is also ...
