SUMMARY
A centrifuge operates based on the principle of centrifugal force, which separates substances by density. When a sample is spun, denser materials move towards the bottom of the container while less dense materials rise to the top. The equation governing this separation is derived from Newton's second law, relating force, mass, and acceleration. In the case of centrifuging blood, plasma, being less dense, collects at the top, while blood cells, being denser, settle at the bottom.
