Question

explain why it is possible to swing the leg in Circles at the hip joint not at the knee joint​

Answer 1

Answer:

The joint in the hips is ball and socket joint and in the knees it is hinge joint.

Explanation:

The ball and socket joint helps movement in all directions and is present in the shoulders and hips , whereas the hinge joint helps in front and back movement (like opening and closing of a door) and is present in the knees and arms.

Therefore you can swing the legs in circles but not your knees.
