1
Q
average speed =
A
distance travelled/ time taken
2
Q
acceleration =
A
change in velocity/ time taken a = (v-u)/t
3
Q
force =
A
mass x acceleration F = ma
4
Q
weight =
A
mass x gravitational field strength w = mg
5
Q
momentum =
A
mass x velocity p = mv
6
Q
moment =
A
force x perpendicular distance from pivot moment = F x d
7
Q
sum of anticlockwise moment =
A
sum of clockwise moment
