Homework Statement


what are the units of the slope of a velocity^2 vs. centripetal force plot? and why should the line pass through the origin?


Homework Equations





The Attempt at a Solution


I'm getting m/km for units but I'm not sure what that actually means so I don't know why it should go through the origin of the graph.

Welcome to the forum!

According first to the relevant equations we got the following:

Centripetal Force = [tex]\frac{mass * velocity^2}{radius}[/tex]

By this we deduce that such a slope of velocity would lead us to be:

m =[tex]\frac{mass}{radius}[/tex]

That is mainly due because we have set up the Centripetal Force to be the Y axis and the velocity square in the X one.

Hope that helped, you may try now work out the math to see why does it pass through the origin.
