Talk to any physicist or at least any one who
has taken a physics class and try to say the word centrifugal force. They will
just laugh at you while thinking you are an idiot.
By breaking up the word into its roots yields…
As explained earlier, the acceleration of an object while in uniform circular motion is always
towards the center of the circle. So of course the word centrifugal is utterly
absurd and physically impossible.
DON’T SAY IT!
The reason that people get the words confused
is because when they are on a merry-go-round you can feel your body being “thrown” outward, but in reality the
ride is not throwing your body outward, rather your body, due to inertia, wants to maintain going in a straight line but is
forced to go in a circle. The outward force you are feeling is not due to the
circle pushing you out, but rather inertia (laziness)
An easy way to demonstrate this is to place a tennis-ball on a white board. Carefully move the board in a straight line then cause it to make a sharp turn, in effect causing the ball
to undergo centripetal motion. The ball will continue to go in the straight line
path and eventually role off the board.
