Conservation of Energy states от The initial energy in a closed system remains constant Fossil fuels should be rationed more thoughtfully. Energy cannot be created or destroyed. The total energy of a closed system is the sum of the Kinetic, Potential, and Heat.

Part A State the law of conservation of energy The law of conservation of energy states that energy can neither be created or destroyed. Energy can be transferred from one object to another, and it can assume different forms. The law of conservation of energy states that energy can not be created but it can be destroyed. Energy can be transferred from one object to another can be destroyed in a chemical reaction, and it can assumo different forms The...

A group of students perform the same "Conservation of Mechanical Energy" experiment that you performed in lab by allowing a solid sphere and then a solid cylinder to roll down the ramp. The solid sphere was released from a height of 12.9 cm. From what height hcylinder should the solid cylinder be released so that it has the same speed as the solid sphere when it reaches the bottom of the ramp?
