Question

Centripetal Acceleration and Newton’s 2nd Law Lab

Q1. Starting with ar = v ^2 /r, show that for any object moving in a circle with constant centripetal acceleration ar pulling inwards, the theoretical rotation period is given by Pth = 2πr v = 2π r ar .

Q2. Does the rotation period change with increased tension in the way you would expect from theoretical grounds? If you increase the tension by pulling down on the hanging mass while the rubber stopper is rotating, what happens?
the results for yourself and for the other members of your group in a table (this time you need to your own table in your lab notebook) listing the radius and period. Q4. For motion in a vertical circle of radius r, use a free-body diagram to show that the minimum possible speed which will keep la paperclip in contact with the cup/the cup on the tray the string tension 0) is given by v vrg 3. From the relation for minimum speed found in o4 for your circle's rails calculate the

Q3. For motion in a vertical circle of radius r, use a free-body diagram to show that the minimum possible speed which will keep {a paperclip in contact with the cup / the cup on the tray / the string tension > 0} is given by € v ≥ rg.
