Physics GCSE eqBR
| 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 |
