equations of motion

Question 1

equations of motion

Answer 1

1. v = u = at
2. s = ut + 1/2at*2
3. v2 = u2 + 2as
4. v(av) = s/t

Question 2

symbols

Answer 2

u = initial velocity
v = final velocity/speed
a = acceleration
t = time
s = displacement/distance

Question 3

units

Answer 3

Velocity: m/s or ms-1
Acceleration: m/s/s or ms-2
Time: seconds
Distance/displacement: metres/m
