Given that objects that have mass greater than 0, by number, identify all of the following four statements that are TRUE: 1) momentum is a form of energy; 2) if an object has momentum, then it must also have mechanical energy; 3) if an object does not have momentum, then it does not have mechanical energy either; 4) if two objects of different mass have the same momentum, then the less massive object will have the greater kinetic energy.
