Question

Which of the following is not equivalent to the formula for angular velocity, v = wr?
vw = r
= r
= 1
= w

Answer 1

I am not sure I understand the question.

Given v = wr, but what are the choices?

Answer 2

vw=r
v/w=r
v/wr=1
v/r=w

Answer 3

Ok -- so v = wr

What happens if we divide both sides of this equation by w?

Answer 4

v/w=r

Answer 5

So that one is equivalent. Further divide that equation by r.

Answer 6

I.e., divide both sides by r

Answer 7

is the answer v/wr=1?

Answer 8

Nope, because that answer is also equivalent. We are using process of elimination. Now multiply both sides by w, what do we get?
