- Which of the following four objects has different kinetic energy than the three others? a) An object of mass 2m moving with speed 5v b) An object of mass 5m moving with speed 2v c) An object of mass 50m moving with speed v d) An object of mass (1/2)m moving with speed 10vHello, I need some help with this problem?I'm trying to understand the different types of energies. I understand the definitions, but when I apply them to situations, it doesn't make much sense to me. I have the following: A. Entrophy - measure of the amt of disorder, or randomness in a system B. Kinetic Energy - Energy in Motion C. Heat - kinetic energy contained in the random motion of atoms & molecules D. Chemical Energy - type of potential energy which arises from the arrangement of atoms and be release in chemical reactions E. Conservation of Energy: Kinetic to Potential Energy - its not possible to destroy or create energy F. Conservation of Energy: Potential to Kinetic G. Potential Energy - Energy an object has because of its location or structure When I try to apply to the following, I come up with this: A: A Glass falls off the shelf & breaks B. An orange falling from a tree C. During exercise you get extremely hot. D Animals consume food (organic molecules) to make ATP to walk, breathe, etc. E. A large…
