Work, Energy And Power Flashcards
1
Q
Work- energy theorem
A
The net/total work done on an object is equal to the change in the object’s kinetic energy.
2
Q
Conservative force
A
A force for which the work done in moving an object between two points is independent of the path taken.
3
Q
Non - conservative force
A
A force for which the work done in moving an object between two points depends on the path taken .
4
Q
State the principle of conservation of mechanical energy
A
The total mechanical energy in an isolated system remains constant.
5
Q
Power
A
The rate at which work is done or energy is expended.
