I don't know what formula to use guys :( my brain is hurting from organic chem overload.

Kinetic energy is the energy an object possesses due to its motion. It is dependent on the object's mass and velocity.
Potential energy is the energy an object possesses due to its position or state, such as gravitational potential energy or chemical potential energy. Unlike kinetic energy, potential energy is not dependent on an object's motion.
Yes, kinetic energy can be converted into potential energy and vice versa. For example, when a roller coaster reaches the top of a hill, its kinetic energy is converted into potential energy, and then back into kinetic energy as it goes down the hill.
Mechanical energy is the sum of an object's kinetic and potential energy. It represents the total energy available to do work.
Temperature is directly related to the average kinetic energy of the particles in a substance. As temperature increases, the average kinetic energy of the particles also increases.
