uniformly accelerated motion

↳ equations of motion :




5 displacement (m)
= v =
u + at
=
= initial
velocity (ms) S =
ut +
zat

= Final velocity (ms) v == u+ zas
=
= acceleration (ms) S = (v + u) +
2


t =
time(s)

example




u= 21 mst v =
a+ at


a = -
3 .
2 ms- 0 =
22 + + (
-
3 .
2)

V = 0 ms + =

... 6 65 .

example




S = -
325m vi = u + 2as


u =
