2. 1ST
EQUATION OF
MOTION
 acceleration =change in velocity
 Total time taken
 a = BA
DA
a = CD
OC
a = OD-OC
OE
a = V-U
T
V = U + aT

3. SECOND EQUATION OF
MOTION
Distance = area of trapezium [shown in graph]
Distance or s = ½ (OD+BE) x h
 s = ½ (u+v)x t
 s = ½ (u+u+at) x t [v = u+at by 1st
of
equation motion]
 s = ½ (2u+at) x t
 s = 2ut + at^2
2 2

s = ut + ½ at^2

4. THIRD EQUATION OF
MOTION
Distance = area of trapezium [shown in graph]
Distance or s = ½ (OD+BE or BE+OD) x h
 s = ½ (v+u) x t
 s = ½ (v+u) x v-u [v =u+at then t = v-u ]
a a]
 s = v^2 –u^2
 a

2as = v^2 –u^2
