Bryan Spelhaug Tues Lab 8:00am Experiment VIII: Centripetal Force Date: 9/14/10 Objective: In this experiment, we will be investigating the effects of angular speed and centripetal force on an object spinning in a circle. Whenever an object moves in a circular path we know the object is accelerating because the velocity is constantly changing direction. All accelerations are caused by a net force acting on an object. In the case of an object moving in a circular path, the net force is a special force called the centripetal force. We will be calculating the centripetal force on a trolley cart moving in a circular path by giving the wheel, which the trolley cart is sitting on, a spin. This spin will cause the trolley to have a force act on it in the direction towards the center of the wheel. Method: For this lab we will be using a turntable that has a track attached to it. The table is aloud to move in a circular direction by giving it a spin. A trolley cart will be placed on the table top in a rail track.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
