Energy Flashcards
1
Q
Kinetic Energy =
A
kinetic energy = 0.5 x mass x (speed)^2
2
Q
elastic potential energy =
A
elastic potential energy = 0.5 x spring constant x (extension)^2
3
Q
gravitational potential energy =
A
gpe = mass x gravitational field strength x height
4
Q
change in thermal energy =
A
change in thermal energy = mass x specific heat capacity x temperature change
5
Q
power =
A
power = work done / time
6
Q
efficiency =
A
efficiency = useful power output / total power input
