Pressure?

Force / area

P = F/A

Distance travelled?

Speed x time

S = v t

Acceleration?

Change in velocity / time taken

a = v - u / t

Wave speed?

Frequency x wavelength

V = f x wavelength

Period?

1 / frequency

Newton’s 2nd Law?

Acceleration = force / mass

a = F / m

Weight?

Mass x gravitational field strength

w = m g

Work done?

Force x distance moved

W = F D

Hooke’s law?

Force = spring constant x spring extension

F = k e

Efficiency?

Useful energy / Energy put in x100

E= useful/input x100

Velocity²?

this is on the formula sheet

Initial velocity² + 2 x Acceleration x Displacement

v²=u²+2as

(this is on the formula sheet)

Elastic potential energy?

this is on the formula sheet

1/2 x Spring constant x Extension²

Ee=1/2ke²

(this is on the formula sheet)

Transformer?

this is on the formula sheet

Np/Ns = Vp/Vs

Moments?

M = F x d

Pressure at a certain depth due to the column of liquid above?

(this is on the formula sheet)

Pressure = depth x field strength x density

p=hρg

(this is on the formula sheet)

Momentum?

Mass x Velocity

m = m x v

Force (in terms of momentum)?

this is on the formula sheet
