1
Q
moment of a force
A
moment of a force = force x distance
2
Q
distance travelled
A
distance travelled = speed x time
3
Q
acceleration
A
acceleration = change in velocity / time taken
4
Q
weight
A
weight = mass x gravitational field strength
5
Q
force applied to a spring
A
forced applied to a spring = spring constant x extension
6
Q
resultant force
A
resultant force = mass x acceleration
7
Q
momentum
A
momentum = mass x velocity
8
Q
pressure
A
pressure = force normal to that surface / area of that surface
9
Q
wave speed
A
wave speed = frequency x wavelength
