Question

in
A particle is moving on a circle with increasing speed in clockwise sense. Its angular
momentum about the centre is
2.5
(a) constant
(b) constant only in direction, but not in magnitude
(d) changing in both the direction and magnitude
c) constant only in magnitude, but not in direction​

Answer 1

Angular momentum is defined, mathematically, as L=Iω, or L=rxp. Which is the moment of inertia times the angular velocity, or the radius of the object crossed with the linear momentum. In a closed system, angular momentum is conserved in all directions after a collision.
