I completed a centripetal force experiment with a rotatingmassattached to a horizontal spring, measured various radii,withcalculated time period of 50 revolutions, a measured forceequal toforce of gravity attached to mass and string/pulleyandexperimental force using F cent = 4pi^2 (mass)/( T^2)* r. Ihadsome questions i was unsure about from post-labdiscussion. 1) Why should the total hanging weight equal the net forceonthe rotating mass? 2)how does the centripetal force vary with the radius ofthepath if the angular velocity remains the same? 3)Find the slope of the line of your F vs r graph.Discusswhatthe slope should be and whether the value you foundisreasonable.[you can use the slope of the line to find the mass,M,you should support your discussion with a calculation ofanappropriate percent difference.
