Description
| Question | Answer |
| P=VxI | Power= voltage x current |
| V=IxR | Voltage= Current x resistance |
| Q=Ixt | charge= Current x time |
| E=VxQ | Energy= voltage x charge |
| E = V x I x t | energy = voltage x current x time |
| Efficiency (%) | (useful energy out ÷ total energy in) x 100 |
| GPE = mgh | GRAVITATIONAL POTENTIAL ENERGY = mass x gravity x height. |
| KE = ½mv2. | kinetic energy = 0.5 x mass x (velocity squared) |
| W = F x d | work done = force x distance. |
| W = E. | work done = energy transferred. |
| P = E ÷ t. | power = energy ÷ time |
| E = c x m x θ | energy = specific heat capacity x mass x change in temperature |
| s = d ÷ t | speed = distance ÷ time |
| a = (v-u) ÷ t | acceleration = change in velocity ÷ time |
| F = m x a | Force = mass x acceleration |
| w = m x g | weight = mass x gravity |
