1
Q

Speed =

A

Speed = distance/time. s = d/t

2
Q

Acceleration =

A
Acceleration = change in velocity/time
a = (v-u)/t
3
Q

Force =

A

Force = mass x acceleration.

F=ma

4
Q

Weight =

A
Weight = mass x gravitational field strength
W = mg
5
Q

Charge Q =

A
Charge = current x time
Q = It
6
Q

Wave Speed =

A

Wave Speed = frequency x wavelength

7
Q

frequency =

A
frequency = 1/time period
f = 1/T
8
Q

Efficiency = useful energy output

A

Efficiency = useful energy output/total energy input

9
Q

Density =

A
Density = mass/volume
p = m/v
10
Q

Pressure =

A

Pressure = Force/Area

11
Q

Pressure in a liquid

A

Pressure in a liquid = depth x density x gravitational field strength
P = hpg
