## Homework Statement

The speed of the pendulum bob remains constant

as it travels around the circle

(a) Over one complete circle, how

much work does the tension force F do on the bob? (i) A positive amount; (ii) a negative

amount; (iii) zero.

(b) Over one complete circle, how much work does the weight do on

the bob? (i) A positive amount; (ii) a negative amount; (iii) zer

## Homework Equations

W = Fs

W = 1/2kmv^2[/B]

## The Attempt at a Solution

I was thinking that work of tension would be negative because it would balance out the work of weight which would be positive? Also, I just took a quiz and it was multiple choice, and the only choice that made sense was this!

The answer that i thought made most sense was that both work would be zero because work total is 0.

Can someone please explain?[/B]
