A rock is thrown straight up from the surface of the Earth.Which one of the following statements describes the energytransformation of the rock as it rises? Neglect air resistance.
Explanation / Answer
Given : A rock is thrown straight up from the surface of theEarth. In this case E ) The kinetic energy decreases and thepotential energy increases Potential enegy is increases with respect toheight. But the total enegy is conserved.Related Questions
