- physics
- acceleration = change in velocity/ time taken
- A = (V - U) / T

- FORCE = MASS * ACELERATION
- F = M * A

- WEIGHT = MASS * ACELERATION DUE TO GRAV
- W = M * G

- MOMENTUM = MASS * VELOCITY
- P = M * A

- MOMENT = FORCE * PERPENDICULAR DISTANCE FROM THE PIVOT
- charge = current * time
- Q = I * T

- voltage = current * resistance
- V = I * R

- power = current * voltage
- P = I * V

- wave speed = frequency * wavelength
- V = F * W

- n = sin i / sin r
- sin c = 1 / n
- efficiency = useful energy output / total energy input
- work done = force * distance
- w = f * d

- gpe = m * g * h
- ke = 0.5 * m * (v*V)
- p = f / m
- p = f / a
- p = h * p * g

- acceleration = change in velocity/ time taken
