Chapter 2 - Work And Energy Flashcards
1
Q
Energy
A
Systems ability to do work
2
Q
Equation for elastic potential energy
Springs!
A
U = 0.5 kx^2
U= potential E K = spring constant X = magnitude of displacement from equilibrium
3
Q
POwer
A
W/t = ∆E/t
Measured in Watts
4
Q
Work Energy Theorem
A
Wnet = ∆K = Kf-Ki
5
Q
Can work be negative?
A
Yes Daniel, it can
6
Q
Mechanical advantage
A
Ratio of magnitudes of the force exerted on an object (Fout) to force actually applied on the simple machine (Fin)
MA = Fout/Fin
7
Q
Isochoric
A
No change in volume
*no work done
