Work, Energy and Power Flashcards
1
Q
the work-energy theorem
A
the work done on an object by a net force is equal to the change in the object’s kinetic energy OR the work done on an object by a net force 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
The principle of conservation of mechanical energy
A
The total mechanical energy (sum of gravitational potential energy and kinetic energy) in an isolated system remains constant
5
Q
power
A
the rate at which work is done or energy is expended.
