Centripetal & Centrifugal

Anonymous asked:
What do centripetal forces and centrifugal forces do?

Centripetal force moves us towards the center. Gravitation is an example of centripetal force. Centrifugal force moves us away from the center. The thrust created by a rocket engine is an example of centrifugal force. To take the example one step further, rockets manage to escape the Earth's gravitational pull (centripetal force) by creating a greater counteracting thrust (centrifugal force).
