5 Work Energy Power Flashcards
1
Q
Work done
A
Product of a force and the displacement in the direction of the force
2
Q
Work done by a gas during expansion
A
W = p (Vf - Vi)
where p is pressure of the gas
3
Q
Energy
A
Ability to do work
4
Q
Principle of Conservation of Energy
A
Energy cannot be created or destroyed, but can be transformed from one form to another, and transferred from one body to another
5
