1

distance

distance = speed x time

2

acceleration

a = (v-u) / t

3

weight

w = mass x gravity or N = kg * N/kg

4

momentum

momentum (p) = mass x velocity

5

gravitational potential energy

gpe = m * g * h

6

kinetic energy

(1/2mass) x v^2

7

efficiency

efficiency = useful energy/ total energy

8

wave speed (velocity) involving frequency

v = f * wavelength

9

wave speed (velocity) involving time

v = x/t

10

final velocity^2 - start velocity^2

v^2 - u^2 = 2ax (2 x acceleration x distance)

11

force

f=ma

12

advanced force

f= (mv - mu) / t

13

power/watts

p = e/t

14

work

J = force x distance

15

GPE = what equation and why

kinetic energy, because of the conservation of energy
