What is centrifugal force?


Centrifugal force describes the sensation one has of being pushed outward when moving on a circular path, but it’s not really a force. The feeling of being pushed outwards when speeding round a bend in a car, or on a merry-goround, comes from your preference to move in a straight line. Isaac Newton showed that all objects have inertia and will either stay at rest, or move in a straight line, unless a force acts on them. When you move in a circle there is a force pulling on you, constantly changing your direction from that of a straight line. This is centripetal force and pulls inwards. The feeling of the ‘outward pull’ of centrifugal force is just your natural resistance to this change in direction.
