hi, I am new to physics and math. This my first year taking a physics course. We just had a lab done for centripital force, and I really got confused about this. The lab was not for marks, but I am still very confused I couldn't figure out the relationship between the radius and the Fc, if the speed is always constant what happens when radius is 0? doesn't that produce an infinite calculation? anyways my graph was very weird, because i could not find a relationship, maybe my data from the experiment was messed up.. and one more thing, is there anything special for its slope?
