# Circular Motion

The wheels on the bus go round and round, but can you name all the forces in a rotating reference frame? Learn to derive these and more through sheer force of reason in Circular Motion.

a) The magnitude of the tensile force \(T\) is greater than that of the gravitational force \(mg\).

b) If we cut off the string right at this moment, then the pendulum will move as if it is thrown to the \(x\) direction.

c) The direction of the net force acting on the pendulum is the \(y\) direction.

**decrease** the chance of the bus toppling?
