Thanks, guys!

Do you need help rearranging equations?

anonymous · Answer

Why is it F/r and not r/F?

chaise · Answer

Your original question is:

$$F = kr$$

If we divide both left and right sides of the equal sign by 'r'. F gets divded by r, and the k and r get divded by r. Because there is a 'multiplication' between k and r we are able to cancle the division on the right hand side. Which lives us with:

F/r = k

diyadiya · Answer

F=k*r
when we bring r to opposite side it becomes division..
F/r=k

Oh, I see. Ha, I was trying to move the k over, and then the F over. Totally wrong. I understand now. Thanks!
