1
Q

Pressure?

A

Force / area

P = F/A

2
Q

Distance travelled?

A

Speed x time

S = v t

3
Q

Acceleration?

A

Change in velocity / time taken

a = v - u / t

4
Q

Wave speed?

A

Frequency x wavelength

V = f x wavelength

5
Q

Period?

A

1 / frequency

6
Q

Newton’s 2nd Law?

A

Acceleration = force / mass

a = F / m

7
Q

Weight?

A

Mass x gravitational field strength

w = m g

8
Q

Work done?

A

Force x distance moved

W = F D

9
Q

Hooke’s law?

A

Force = spring constant x spring extension

F = k e

10
Q

Efficiency?

A

Useful energy / Energy put in x100

E= useful/input x100

Q

Velocity²?

this is on the formula sheet

A

Initial velocity² + 2 x Acceleration x Displacement

v²=u²+2as

(this is on the formula sheet)

12
Q

Elastic potential energy?

this is on the formula sheet

A

1/2 x Spring constant x Extension²

Ee=1/2ke²

(this is on the formula sheet)

13

Np/Ns = Vp/Vs

this is on the formula sheet

14
Q

Moments?

A

M = F x d

15
Q

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

(this is on the formula sheet)

A

Pressure = depth x field strength x density

p=hρg

(this is on the formula sheet)

16
Q

Momentum?

A

Mass x Velocity

m = m x v

17
Q

Force (in terms of momentum)?

this is on the formula sheet

A

Change in momentum / time taken

F = ΔP / Δt

(this is on the formula sheet)
