1

Weight=

M x g
(Mass x gravitational field strength)

2

Force=

K x e
(Spring constant x extension)

3

Work done=

F x d
(Force x distance moved in direction of force)

4

Power=

E/t
(Energy / time taken)

5

Ep=
(Change in gravitational field strength)

M x g x h
(Mass x gravitational field strength x change in height)

6

Ek=
(Kinetic energy)

1/2 x m x v2
(half x mass x velocity squared)

7

A=
(Acceleration)

(V-u)/t
(final velocity subtract initial velocity divided by time taken)

8

GPE=
(Gravitational potential energy)

M x gfs x h
(Mass x gravitational field strength x height)

9

EPE=
(Elastic potential energy)

0.5 x k x e2
(Half x spring constant x extension squared)

10

Specific heat capacity=

M x c x t
(Mass x capacity x temp change)
