Can anyone help with this misconception.
Take a particle mass m moving in a vertical circle speed v.
At the lowest point applying F=ma we have T-mg = (mv^2)/r. Ok that's fine.
At the highest point we have T+mg =(mv^2)/r , this is where I am getting confused both the tension and weight act down so what is keeping the particle up? Is there another force at play? How do we quantify it?
