Work, Energy and Power Flashcards
1
Q
Work
A
Work done by a constant force, where F is the magnitude of the force, delta x in the magnitude of the displacement and theta is the angle between the force and displacement
2
Q
Work Energy Theorem
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 of the path taken (Fg and Fn)
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 (Fk, Fa and T)
5
Q
Principle of Conservation of Mechanical Energy
A
Total mechanical energy (Fg + Fk) in an isolated system remains constant
6
Q
Power
A
The rate at which work is done
