A
Work is the mechanical transfer of energy to a system or from a system by an external force on it.
2
Q
Heat
A
Heat is the non-mechanical transfer of energy from the environment to the system or from the system to the environment because of a temperature difference between the two.
3
Q
Principle of conservation of energy
A
The principle of conservation of energy-states that energy cannot be created nor destroyed in any process.
4

A
Gravitational Potential Energy is defined as the amount of work done in order to raise the body to the height h from a reference level.
5
Q
