WARNING!!! Centripetal Force is not a new, separate force created by nature! Some other force creates centripetal force Swinging something from a string  tension Satellite in orbit  gravity Car going around curve  friction

Recall: Newton’s Law of Universal Gravitation Magnitude: Every particle in the universe attracts every other particle with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them. Direction: This force acts along the line joining the two particles.
