1
Q
speed
A
distance / time
2
Q
force
A
mass x acceleration
3
Q
momentum
A
mass x velocity
4
Q
density
A
mass / volume
5
Q
acceleration
A
change in velocity / time taken
6
Q
work done
A
force x distance moved
7
Q
energy relationships
A
energy transferred = work done
kinetic energy = 1/2 x mass x speed^2
gravitational potential energy = mass x g x height
8
Q
weight
A
= mass x gravitational field strength
9
Q
pressure
A
force / area
10
Q
moment
A
force x perpendicular distance from the pivot
