You may wonder why the roller coaster keep moving swing like a pendulum and move below with the highest velocity.Do you know,the roller coaster keeps moving up and down,horizontal and vertical because it has the kinetic,potential and mechanical energy.
Hints:Mechanical energy-Total of kinetic and potential energy.
Potential energy:Energy that stored in object at the highest place[can be in elastic object].
Kinetic energy:Energy that stored in moving object.
Heat energy:Energy that stored in hot object.
1)The mechanical energy
When we moving while hiking over the top,it is call the mechanical energy.It is the same principle as the roller coaster did.When it is moving until the top it would be called the mechanical energy.
2)The potential energy
After we reach to the top,we will get the potential energy.Then,it will turn to the last one,kinetic energy.
3)The kinetic energy
Finally,it would turn the potential energy to kinetic energy and it will roll over and over until it's turn to heat energy.
The easiest way
Mechanical-Potential=Kinetic=Heat
