Answer: objects in move has Kinetic energy
Objects who does not move have only potential energy
Explanation:
E=Ek+Ep
Ek kinetic energy
Ep-potential gravitational energy
Ek =mV²/2
Ep=mGh
If object moves has speed .
if object does not move speed is 0.Mechanical energy is : E=Ek+Ep
if V=0
E=Ep
if object is moving E=Ek
