1
Q
what is distance?
A
2
Q
what is displacement?
A
3
Q
what is speed?
A
the rate of change of distance
average speed = tot. distance moved / tot. time taken
4
Q
what is velocity?
A
the rate of change of displacement?
average velocity = tot. displacement / tot. time taken
5
Q
what is acceleration?
A
the rate of change of velocity
average acceleration = change in velocity / time taken
6
Q
equations of motion
A
v = u + at
s = ut + 1/2at^2
v^2 = u^2 + 2as
7
Q
