Average speed |
Average speed = distance moved ÷ time taken |
|
|
Acceleration |
Acceleration = change in velocity ÷ time taken a = (v - u) ÷ t |
|
|
Force (using mass) |
Force = mass × acceleration |
|
|
Force (using change in momentum) |
Force = change in momentum ÷ time taken |
|
|
Weight |
Weight = mass × g |
|
|
Momentum |
Momentum = mass × velocity |
|
|
Moment |
Moment = force × perpendicular distance from the pivot |
|
|
Power |
Power = current × voltage P = I × V |
|
|
Voltage |
Voltage = current × resistance V = I × R |
|
|
Charge |
Charge = current × time Q = I × t |
|
|
Efficiency |
Efficiency = useful energy output ÷ total energy input |
|
|
Work done |
Work done = force × distance moved W = F × d |
|
|
Gravitational potential energy |
Gravitational potential energy = mass × g × height GPE = m × g × h |
|
|
Kinetic energy |
Kinetic energy = 1/2 × mass × speed squared KE = 1/2 × m × v^2 |
