Question 560: Centre of Mass and Rotational Motion

Question

A particle moves along a circular path with decreasing speed. Hence

Accepted Answer

The direction of angular moment remains constant as the angular momentum is a vector quantity, and its direction is perpendicular to the plane of motion. As the speed decreases, the linear momentum decreases, but the angular momentum remains constant due to the conservation of angular momentum.

Answer

its resultant acceleration is towards the centre.

Answer

it moves in a spiral path with decreasing radius.

Answer

the direction of angular momentum remains constant.

Answer

its angular momentum remains constant
