What is kinetic energy to thermal energy?
If a Roller Coaster has a potential energy at the top of the hill 10000 Joules then what amount of kinetic energy does it have when it is 1/4 of the way above the ground?
What is 7500 Joules?
On a roller coaster with point "W" at the very top of the hill and point "X" at the very bottom of the drop, point "W" represents maximum of this energy, while point "X" represents the maximum of this energy. When we put these two forms of energy together, we have this form of energy.
Potential energy at W, Kinetic Energy at X, and together they create Mechanical Energy.
