Question | Answer |
---|---|
Average speed | v = d/t |
Acceleration | a = (v - u) / t v - final u - initial |
Force | F = ma |
Weight | W = mg |
Momentum | p = mv |
Moment | = Force * perpendicular distance from pivot |
Moments [2] | Sum of anti-clockwise moment = sum of clockwise moment |
Power | P = IV |
Energy | P * t (power * time) |
Current | I = Q/T |
Voltage | V = IR |
Wavespeed | v = fλ |
Refractive index | Sin(i) / Sin(r) |
Refractive index [2] | n = 1/Sin(c) |
Work done | W = F * d |
Gravitational potential energy | GPE = mgh |
Kinetic energy | KE = ½mv² |
Power | Work done / time taken w/t |
Density | Rho = m/v |
Pressure | Pressure = Rho * g * h |
Pressure [2] T = temperature | P1/T1 = P2/T2 |
Transformers | input v/output v = primary turns/secondary turns |
