Equations Of Motion

Question 1

Acceleration

Answer 1

• acceleration = change in velocity(m/s)
     (m/s2)            ———————————
                             Time taken (s)

• a = (v-u)
——
T

• a = acceleration
• v = final velocity
• u = initial velocity
• t = time taken

Question 2

Velocity

Answer 2

•(Final velocity)2 - (initial velocity)2
=
2 x acceleration x distance

•v2-u2 = 2 X a X x

(x is distance traveled)

•v2= u2 + 2ax
