The force which pulls an object toward the center of a circle is called centripetal force. How much centripetal force needs to be exerted to cause an object to move in a circle? Your experience should tell you that the amount of centripetal force that you need to exert depends on the mass of the object you are whirling, how fast you are whirling it and the radius of the circle.
We will use an apparatus similar to the one pictured below to measure the effect of speed on centripetal force. You can hold the mass constant during a set of trials by always whirling the same object. You can keep the radius of the circle constant (with a little practice) by keeping the upper paper clip a fixed distance below the tube while whirling the object.
I’m uploading a complete virson work by my firend, you can copy his data, make some changes and use it in mine work, that’s fine. After that just follow the guide in the excel. The questions are the same , but I need you to do another virson base on your make up data
