Energy is transferred between stores - Thermal, kinetic, gravitational potential, elastic potential, chemical, magnetic, electrostatic, nuclear Energy is transferred... - Mechanically (by a force doing work), electrically (work done by moving charges), by heating or by radiation (like light or sound) When a system changes, energy is transferred - It can be transferred into or away from the system, between objects in the system or between different types of energy stores. Closed systems are...

KPE160 DOUG PREP QUESTIONS AND ANSWERS 100% PASS Centre of Gravity vs Centre of Mass - Answer- centre of mass depends on the distribution of mass (not gravitational field) and it doesn't change even if you move or orient yourself differently. Centre of gravity is a unique point which weight is balanced, it can change based on orientation and also takes into account mass distribution. Is it harder to lift or lower a mass? Which feels harder and why? - Answer- It takes the same amount of f...
