- Energy Dissipation
- When there is a change of energy in a system, some of that energy is transferred and some energy is dissipated
- Any energy that is not transferred is said to be wasted as it is lost to the surroundings
- In a mechanical energy system energy is dissipated when two surfaces rub together.
- Work is done against friction which causes the two surfaces to heat up, this leads to an increase in thermal energy
- Adding a lubricant to the surface will reduce friction so less heat energy is wasted
- Conservation Of Energy
- Energy can be transferred usefully, stored or dissipated. It can't be created or destroyed.
