Question

Hello! I am currently looking better to understand energy applications from energy and Its Applications. I have a screenshot of the work I am currently doing right now. I know it's pretty straightforward; however, I wanted to understand better since I now don't know how to write the explanation.

Answer 1

Q2

The different types of energy that this system has are mechanical energies. These wans describes the movements and position of objects.

- Kinetic energy, due to speed

- Potential energy, due to high and gravity

- Losses like friction, due to contact between cart and structure. This refearse to the contact between two surface that reduce the speed and generates losses at any system.

Q3

The mechanical energy try to be constant so there is a traid off between kinetic energy and pontential energy. The kinetic E is higher when the potential E is lower, it means that the speed is higher when the high is lower.

Q1

The energy is potential because the high is the maximum possible. On the other hand the speed is 0, is not moving so the kinetic energy is 0 too.
