Can energy be lost as heat
WebJul 11, 2024 · In partially inelastic collision, the objects involved in the collisions do not stick, but some kinetic energy is still lost. Friction, sound and heat are some ways the kinetic energy can be lost through partial inelastic collisions. Suppose there are two blocks on a frictionless surface. These blocks undergo partially inelastic collision. There are also significant energy losses within a car's internal combustion engine. The chemical energy from the gasoline (or diesel) - which originates from the Sun as it is a fossil fuel - is then converted into heat energy, which presses on pistons in the engine. The mechanical energy is then transported to the wheels … See more Energy undergoes many conversions and takes on many different forms as it moves. Every conversion that it undergoes has some associated … See more Electricity use is a good example that illustrates energy loss in a system. By the time the energy associated with electric power reaches the user, it has taken many forms. Initially, the … See more
