Imagine an object held at some height above the ground. It is released and falls toward the ground. Ignoring air resistance or friction, which of the following must be true? (1 point) Before it falls, all of its energy must be potential energy
At the end of its fall, all of its energy must be converted to kinetic energy
During its fall, the combination of its kinetic and potential energy must equal the amount of potential energy with which it started
Total energy = Kinetic Energy + Potential Energy
All of the above
