QUESTION:

Show on a diagram how your CM shifts when you move from a lying position to a sitting position.

ANSWER:

Step 1 of 3

We have to draw a diagram indicating the position of center of mass(CM) of the body in a lying and sitting position.

Concept:

Center of mass of a body is an imaginary point at which the whole mass of the body is supposed to be concentrated.

We consider that the net force acts on the center of mass of the body, instead of considering that it acts on each and every point on the body for simpler calculation.
