Topic 1 - Energy Flashcards
1
Q
Kinetic Energy
A
Kinetic Energy = 1/2 m x v^2 (half of mass x velocity squared)
2
Q
Gravitational Potential Energy
A
GPE = mgh (mass x gravitational field strength x height)
3
Q
Power
A
Work done ÷ time taken
Energy transferred ÷ time taken
4
Q
Efficiency
A
Useful energy output ÷ total energy input
Useful power output ÷ total power input
5
Q
Elastic Potential Energy
A
Elastic Potential Energy = 1/2k x 𝑥^2 (half of springy constant x extension from original length squared)
6
Q
Specific Heat Capacity
A
Energy transferred = mass x specific heat capacity x temperature change
7
Q
Weight
A
Weight = Mass x Gravitational Field Strength
8
Q
Work Done
A
Work Done = Force x Distance
