A roller coaster car is traveling on a track without any friction or added energy. The people, car, and track of the roller coaster can be analyzed as a single . The total amount of in the roller coaster system is the same at all times. Any increase in the car’s kinetic energy equals a decrease in the system’s .

Respuesta :

System

energy

potential energy

Any increase in the car’s kinetic energy equals a decrease in the system’s potential energy.

What is law of conservation of energy?

The law of conservation of energy states that energy can neither be created nor be destroyed , it only get transform from one form of energy to another form . Sum of kinetic energy and potential energy will remain same

Hence , from law of conservation of energy , it can be written

Total energy = kinetic energy + potential energy

Any increase in the car’s kinetic energy equals a decrease in the system’s potential energy because of energy conservation , energy should remain constant , so if one energy increases other will decrease to maintain total energy constant  and vise versa .
