Explain your answer. (Hint: think about the law of conservation of energy) Conservation of energy tells us that energy cannot be created or destroyed but only transferred from one store to another. Here it is transferred from the gravitational store to the kinetic store.
Energy is often lost from a system via heat energy transferring to the surroundings. By covering an object in a layer or multiple layers of a material, you can reduce the rate of heat transfer out of the object. This is called insulation. For example, when you get cold, you might put on a coat.
Law of conservation of energy states that energy cannot be created or destroyed. Under this law, it is possible that energy can be transferred from one energy store to another, using one of four transfer methods:
Worksheet #8: Conservation of Mechanical Energy Student Name: Energy (E) is defined as the capacity to do work (scalar). The unit for all energy and work is the Joule Mechanical energy- the energy due to the position of something or the movement of something. Mechanical Energy can be divided into to categories:
