P7 Work Done (Combined Science) Flashcards
1
Q
Work Done
A
Work Done = Force x Distance
2
Q
Energy (Thermal)
A
Change in Energy = Mass x Specific Heat Capacity x Temperature Difference
3
Q
Energy (Kinetic)
A
Energy = 0.5 x Mass x (Speed)^2
4
Q
Energy (Gravitational)
A
Energy = Mass x Gravitational Field Strength x Height
5
Q
Energy (Elastic)
A
Energy = (0.5)(Spring Constant) x (Extension)^2
6
Q
Energy (Nuclear)
A
Energy = Mass x (Velocity of Light)^2
7
Q
Power
A
Power = Work Done / Time
8
Q
Efficiency
A
Efficiency = Useful Output Energy Transfer / Input Energy Transfer
