1. The problem statement, all variables and given/known data When an object travels in a horizontal circular motion attached to a string, it is understood that there is a force on the object directed towards the center. What force is acting on it to stop it from moving to the center? 2. Relevant equations Fc = (mv^2)/r 3. The attempt at a solution I know T gets used a lot with these equations, so I am going to guess tension. But, even if this is right, I do not understand where this tension is coming from or how it counter balances the centripetal force.
