Is angular momentum conserved even if torque is present?
1 Answer
Pavan Kumar
yes ,if torque is acting perpendicular to angular momentum then angular momemt is conserved.consider a ball spinning in a bowl(frictionless) two velocities are present horizontal and downward...the horizontal angular momemtum is conserved because it is upward but toque by gravity is tangential that is why while spinning balls rotational speed increases generally

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
