Questions about uniform circular motion (1 Viewer)

I have done a prac on circular motion recently. It involved rotating a ball with a motor. The ball was connected to the motor by a string. We changed the period of the rotation to see how it affects the angle the string makes with the horizontal and the tension force (radius wasnt constant coz of the changes made to the angle). After the prac, i found out that tension force is directly proportional to frequency sqared and the graph of frequency and tension force is a curve. Here are some questions that i need help with.


"wat is the relationship between the horizontal component of tension force and the frequency when the radius remains constant?"

"since tangential speed V is directly proportional to frequency, wat is the relationship between the horizontal component of tension force and the tangential speed V when the radius remains constant?"

=P I really appreciate your help.

A third question >.<

How is the situation of the experiment similar to how the banking of curves provides a force which causes centripetal acceleration?

>.> my physics is pretty bad i need some help with this question too.
