f = frequency
T = period
The floor pushes the
person toward the center
of the circle. Even though
the force is inward, it feels
the opposite.
The ball wants
to go in a
straight line
due to its
inertia
Rolling without slipping
Rolling wheel
All three masses are part of a rigid body that have
the same rotational velocity
Solve for RA and RB
RA + RB = F
τA = 0 = RB(x1 + x2) – Fx1
All parts of rotating disk have
same angular acceleration
