Question

Which of the following statements about an apple falling from a tree is true? A) Its kinetic energy decreases and its potential energy increases. B) Its potential energy decreases and its kinetic energy increases. C) Its kinetic and potential energies remain constant. D) Its mechanical energy increases.

Answer 1

Your answer would be B because potential energy is an object's potential to move while kinetic energy is the energy of the object in motion. So if the apple is falling, then the potential energy would decrease and its kinetic energy would increase. 

Hope this helps :)
