3
Q
ms-1 to kmph
A
/1000 x60 x60
4
Q
uvat
A
v = u + at
5
Q
suat
A
s = ut + 1/2 at^2
6
Q
svat
A
s = vt - 1/2 at^2
7
Q
suva
A
v^2 = u^2 + 2as
8
Q
suvt
A
s = 1/2 (u+v)t
9
Q
Differentiation rules for variable acceleration
A
Differentiate s/x down to get v, v down to get a
10
Q
Distance travelled from a speed time graph
A
Area under the graph
11
Q
Acceleration from a speed time graph
A
Gradient of the graph
12
Q
Acceleration in projectiles
A
Horizontal motion, a = 0
Vertical motion, a = -g
13
Q
How to find speed and direction of motion (projectiles)
A
Pythagoras for speed, tan-1 for direction
14
