Work, Energy And Power Flashcards
1
Q
Define work done
A
The work done by a constant force F where Fdeltaxcostheta where F is the magnitude of the force and delta x the magnitude of the displacement and theta the angle between the force and the displacement.
2
Q
Define net work.
A
The sum of the work done by the individual forces that act on the object.
3
Q
Define work energy theorem.
A
The amount of work done on an object is equal to the change in the object’s kinetic energy.
4
Q
Define power.
A
The rate at which work is done.
