Work, Energy, And Power Flashcards
1
Q
Work
A
Nett work done on an object by a constant force F where F is the magnitude of the force, the magnitude of the displacement and the angle between the force and the displacement
2
Q
Work-energy therom
A
The work done on an object by a net force is equal to the change in the objects kinetic energy
3
Q
Conservative force
A
A force for which the work done in moving an object between two points is independent to the path taken
4
Q
Non-conservative force
A
A force for which the work done in moving an object between two points depends on the path taken
5
Q
Princ. Of conservation of Mech energy
A
The total mechanical energy in an isolated system remains constant
6
Q
Power
A
The rate at which work is done or energy is expended
