Gravity on different worlds
Professor Brian Cox demonstrates the effects of standing on the surface of different planets with an experiment demonstrating the spinning centrifuge. The faster it spins the greater the gravity effect created. The more massive the planet or star the greater its gravity. On Jupiter at 2.5g which is 2.5 times the gravity of earth everything feels heavier. By the time the machine creates 5g a person can no longer see clearly and it becomes difficult to breath. Created especially for Class Clips from the BBC series Wonders of the Universe, first broadcast in April 2011.
