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
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 rock sits on top of the mountain
F. Plantsuse the energy of sunlight to make organic molecules.
G. Gasoline in a portable gasoline container.
Were my descriptions correct? Thanks!

- Hello, can u help me with this question pleasearrow_forwardEnergy can be transferred between objects and it can change forms. a. Give an example of a situation where energy is transferred from one object to another. Make sure to describe which object started off with the energy and where the energy went. b. Give an example of a situation where energy changes from one type to another. Make sure to describe the original form of the energy, and what object causes the change in the type of the energy.arrow_forwardHi! Please help me with this, thank you!arrow_forward

- QUESTION 5 Which of the following statements about energy is not true? The mechanical energy of a physical system is constant when the forces acting on the system are all conservative forces. a. O b. According to the work-energy theorem, the forces that contribute to the net work include all the conservative and nonconservative forces. c. The total energy of the universe is always conserved. O d. Energy can change form, but it cannot be created or destroyed. O e. Mechanical energy is always conserved ONHarrow_forward13. 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 18arrow_forward5.
