D (m) = S (m/s) x T (s)
Distance = Speed x Time
1 of 20
a (m/s²) = (v-u) (m/s) / t (s)
Acceleration = (final velocity - initial velocity) / time
2 of 20
F (N) = m (kg) x a (m/s²)
Force = mass x acceleration
3 of 20
W (N) = m (kg) x g (N/kg)
Weight = mass x gravitational field strength
4 of 20
P (kg m/s) = m (kg) x v (m/s)

Efficiency
Efficiency = useful energy (J) / total energy (J) x 100%
6 of 20
GPE (J) = m (kg) x g (N/kg) x h (m)
Change in gravitational potential energy = mass x change in gravitational field strength x change in vertical height
7 of 20

E (J) = f (N) x d (m)
Work done = force x distance moved in direction of force
11 of 20
P (W) = E (J) / t (s)
Power = work done/time taken
12 of 20
Q (C) = I (A) x t (s)
Charge = current x time
13 of 20
E (J) = Q (C) x V (V)
Energy transferred = charge moved x potential difference
14 of 20
V (V) = I (A) x R (Ω)
Potential difference = current x resistance
15 of 20
P (W) = I (A) x V (V)
Electrical power = current x potential difference
16 of 20
P (W) = E (J) / t (s)
Power = Energy transferred / time taken
