1
Q
what is speed and is it vector or scalar?
A
- how fast something is moving
- scalar
2
Q
what is displacement and is it vector or scalar?
A
- how far an objects travelled from its starting point in a given direction
- vector
3

A
- the rate of change of an object’s displacement
- vector
4

A
- the rate of change of an object’s velocity
- vector
5
Q
what letter symbolises displacement?
A
s
6
Q
what letter symbolises initial velocity?
A
u
7
Q
what letter symbolises final velocity?
A
v
8
Q
what letter symbolises acceleration?
A
a
9
Q
what letter symbolises time?
A
t
10
Q
what is displacement measured in?
A
m
11
Q
what are initial velocity and final velocity measured in?
A
m s^-1
12
Q
what is acceleration measured in?
A
m s^02
13
Q
what is time measured in?
A
s
14
Q
what are the 5 SUVAT equations?
A
- v = u + at
- s = (u + v)/2 x t
- s = ut + 1/2at^2
- v^2 = u^2 + 2as
- s= vt - 1/2at^2
