GR 10 PHYSICS (WORK AND ENERGY) WORKSHEET 1 (QUESTIONS AND MEMORANDUM)
WORK AND ENERGY,
Gravitational Potential Energy: The energy of an object due to its position in a gravitational field relative to some reference point (base level)
Kinetic Energy: The energy of an object due to its motion
Mechanical Energy: The sum of the gravitational potential energy and the kinetic energy of a system.
The Law of Conservation of Energy: Energy cannot be created or destroyed. It can be transformed one type to another. Total energy in the system remains constant.
The Law of Conservation of Mechanical Energy: The total amount of mechanical energy, in a closed system, remains constant.
