What it would look like from the side would be something like this. And to make it simple, let's say this ball is tracing out a perfect circle, and let's say it's sitting onĪ perfectly frictionless table so this would be the bird's eye view. So, to start with, imagine this example, let's say a string is causingĪ ball to rotate in a circle. Misconceptions that people have when they deal with theseĬentripetal motion problems. Solving strategies that you can use as well as going over a lot of the common Gonna go over some examples to give you some problem That many people have when they deal withĬentripetal force problems, so in this video, we're Unfortunately quite a few common misconceptions However, since this is not the case and the payload fired from any catapult travels a parabolic path that can be predicted given the initial velocity and angle of release, we must assume that centrifugal force DOES NOT exist. If centrifugal force DOES exist, then the payload from, let's say, a trebuchet* would first fly and curve higher into the sky, thus violating the law of gravity, a some time before beginning to fall. There is no outwards "centrifugal" force involved - the car is pulling your body out of its straight path and taking your body (against your will) along the curve.Ī situation that disproves centrifugal force would be a catapult. What's happening is your body (which is not attached to the car) tries to follow Newton's 1st Law while the car is in circular motion - you are trying to keep moving straight but the car is impeding your efforts, dragging you to the side. Is this centrifugal force? The answer is no. However, when the car turns left or right, you lean in the opposite direction. While the car is driving straight, you experience no abnormalities. This misconception stems probably from how certain objects that are not part of (or attached to) the moving body experience an outwards pull.įor example, say you are driving in the passenger seat of a car. Centrifugal force is what we call a "pseudo-force" - it doesn't actually exist, but many people believe it does.
