Unformatted text preview: Name: Sharan Multani Name: Nick M3 - Conceptual Questions Q1 .) Consider a disk rotating in the horizontal plane. Point A is located at the edge of the disk and point B is located exactly halfway between the axis of rotation and point A. Which point (A or B) experience larger centripetal acceleration? Perhaps, they have the same centripetal acceleration? Please include your calculations that justify your answer. Ans1 .) We force that Force = mass x acceleration. This equation applies to motion in a linear form. For circular motion, centripetal force is: = * Force mass velocity2radius Therefore, Centripetal Acceleration = velocity2radius As seen in the equation above, centripetal acceleration is inversely proportional to the distance from the center ( r ). As we can see from the diagram above, point A is located at the edge and point B is located somewhere nearer to the center. Points located nearer to the center experience larger amounts of centripetal acceleration....
