Physics Formulae Paper 2

Question 1

Moment of a force

Answer 1

Moment = force (normal to direction of force) x distance
Nm = N x m

Question 2

Distance travelled

Answer 2

Distance travelled = speed x time
m = m/s x s

Question 3

Acceleration

Answer 3

Acceleration = change in velocity / time
m/s squared = m/s / s

Question 4

Resultant force

Answer 4

Resultant force = mass x acceleration
N = kg x m/s squared

Question 5

Momentum

Answer 5

Momentum = mass x velocity
kgm/s = kg x m/s

Question 6

Wave speed

Answer 6

Wave speed = frequency x wavelength
m/s = Hz x m
