 * Objective:** To see how changing the mass, the period, and the radius effects the centripetal force.
 * Video:**

1. While varying the mass between 1, 3, and 6, collect the radius, period, and tension. 2. While varying the period between 1, 2, and 4, collect the mass, radius, and tension. 3. While varying the radius 0.4, 0.6, and 1, collect the mass, period, and tension. 4. Use the equation for Newton's Second Law to find centripetal force:
 * Data Collection Strategies:**

Centripetal Force= [m(2


 * pi*R/T)^2]/R

//Where: m: mass// //T: Period// //R: Radius// //1. How does varying the mass effect the centripetal force?// //2. How does varying the period effect the centripetal force?// //3. How does varying the radius effect the centripetal force?// //4. Which one of these effects the centripetal force the most?// [(Actual-Experimental)/Actual]*100 We use percent difference and not error because we do not know the real centripetal force
 * Analysis Questions:**
 * Graphical Analysis: None**
 * Percent Difference:**
