Answer:
so as we know potential energy is stored energy which is the top of the roller coaster when you increase the pull of gravity you will increase potential energy and kinetic energy is a theory that states that particles of matter are always in motion. and that the amount of motion depends on the amount of energy in the particles so for short kinetic energy is energy in motion which is the roller coaster when its moving. mechanical energy is the same thing energy in motion such as a moving vehicle which is still the roller coaster when its moving. conservation of energy from the roller coaster is not destroyed nor created the energy changes form.
so the potential energy is stored in the top of the roller coaster. kinetic energy is when the roller coaster is in motion same thing for mechanical and conservation is the energy that is being released from the roller coaster is neither destroyed nor created.
