Conservation of Energy + Efficiency Flashcards
1
Q
Conservation of Momentum
A
In an isolated environment, all momentum is conserved
total momentum before = total momentum after
2
Q
Efficiency
A
(useful energy out / total energy in) x 100%
3
Q
Diagram to show efficiency
A
Sankey Diagram
4
Q
Energy that is not transferred into useful energy is…
A
dissipated
energy cannot be lost → it is transferred
