Work, energy and power Flashcards
1
Q
Work- energy theorem
A
The net work done on an object is equal to the change in the object’s kinetic energy.
2
Q
Conservative force
A
Force for which the work done in moving an object between two points independent of the path taken.
3
Q
Non-Conservative force
A
Force for which the work done in moving an object between two points depends on the path taken.
4
Q
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
6
Q
Gravitational potential energy
A
The energy an object has because of its position in the gravitational field relative to some reference point.
