| final velocity v | = u + at |
| unbalanced Force F | = ma |
| Kinetic energy KE | = 0.5 mv^2 |
| Potential Energy PE | = mgh |
| Work done WD | = Force x distance |
| average speed | = total distance / total time |
| Voltage V | = IR |
| Charge Q | = It |
| Power P | = Energy / time |
| Momentum | = mv |
| time | distance / average speed |
| Weight W | = mg |
| Resistance R | = V/I |
| Total resistance in Series | = R1+ R2 +R3 +..... |
| Electrical Power | = ItV |
| Lawof reflection | angle i = angle r |
| % efficiency | =useful work done/ total energy used |
| acceleration | = change in speed / time |
| distance s | = ut + 0.5 at^2 |
| v^2 | = u^2 + 2as |
| work done W | = force x displacement |
| Power P | = (work done or energy changed) / time taken |
| Electric Charge | = current x time |
| Voltage, V | = work done / charge |
| Resistance, R | = voltage / current |
| Power P | = VI = RI^2 |
| Heat Energy E | = mc(delta t) |
| EMF E | = V + Ir |
| the wave equation v | = frequency x wavelength |
| speed of wave on a string v | =sqrt(T/m) |
