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…

13. You learned in Science that Energy is conserved, that Potential Energy must balance Kinetic energy. Mathematically, that means: 1 mgh =-mv², where mgh is Potential %3D Energy 1 and -mv² is Kinetic energy. Reminder that m is 2 mass, g is the acceleration due to gravity, h is height and v is velocity. a) Balance this equation such that the sum of Potential and Kinetic Energy is zero (hint: gravity is negative). b) Solve this equation for v; again, you only need the Algebra you've learned! (hint: don't worry about the negative at the end!) Show your work! + tv MAR 18
