m

Question 11

what are initial velocity and final velocity measured in?

Answer 11

m s^-1

Question 12

what is acceleration measured in?

Answer 12

m s^02

Question 13

what is time measured in?

Answer 13

s

Question 14

what are the 5 SUVAT equations?

Answer 14

1. v = u + at
2. s = (u + v)/2 x t
3. s = ut + 1/2at^2
4. v^2 = u^2 + 2as
5. s= vt - 1/2at^2
