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…

On a horizontal surface with µk = 0.70, a 5kg object is dragged with 350N force directed due East. a. Draw all forces, and calculate the work done by each force if the object moves from 3 m to 10 m on the x-axis. Calculate the total work.
Bugs Bunny (m=32 kg) starts at rest atop a h;=33 m tall hill, and then slides down. After that, Bugs: I.) slides into a swing set at the bottom of the hill, which has a R = 11 m long chain. He swings up and over the bar, with the chain managing to stay taut. (Labelled points A, B & C are at the bottom, side and top of the loop respectively.) II.) continues on flat ground, where he then hits a friction patch which is L=41.25 m long, from which he exits (at labelled point D) at speed vD = 17.98 m/s. III.) slides off a cliff that is hp=17 m tall, into a lake. h, D R Part I: (around the swing set) a.) Sketch in the correct directions of all forces that act on Bugs at each of the points A-C. Note: At point A, Bugs has already lifted his feet off the ground. B
