- How fast must a 2.5-g ping-pong ball move in order to have the same kinetic energy as a 145 g baseball moving at 32.0 m/s? m/s Physical ConstantsI'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…Question 1 The first question does not require the coefficient of friction. Doesn't all the work being performed by the system = friction? Friction is the only thing that is performing work?
