Work and energy Flashcards
1
Q
Kinetic Energy
A
1/2mv2
2
Q
Potential Energy
A
Gravitational = mgh
Elastic = 1/2kx2
- k: spring constant
- x: displacement from equilibrium
3
Q
Work
A
= F x d = Fd cosØ
Theta is the angle between the applied force vector and the displacement vector
In systems where the pressure doesn’t change (isobaric), work = P x (Vf - Vi)
