8.6 - more calc on motion along a straight line

Question 1

State what each word stands for, with their desired units

S

U

V

A

T

Answer 1

S = displacment (m)

U = inital velocity (ms^-1)

V = final velocity (ms^-1)

A = acclertaion (ms^-2)

T = time (s)

Question 2

state the 5 main SUVAT equations

Answer 2

v = u + at

S = 0.5(v+u)t

s = ut + 0.5at² OR s = vt - 0.5at²

v² = u² + 2as

Question 3

2 staged suvat questions

1- when do you know to move onto the second stage

2- what is the link between the 2 stages

Answer 3

1-the acceleration changes

2- the v of the first stage = u of the next stage
