Work, Energy, Power Flashcards
1
Q
Work-energy theorem
A
The net work done on an object is equal to the change in the objects kinetic energy
2
Q
Conservative force
A
Force for which work done in a moving object between 2 points is independent of path taken
3
Q
Non conservative force
A
Force which work done in moving object between 2 points depends on path taken
4
Q
Principle of conservation of mechanical energy.
A
Total mechanical energy (sum of gravitational potential energy & kinetic energy) in an isolated system remains constant. (A system is isolated when net external force acting on system is zero)
5
Q
Power
A
Rate at which work is done
