Distinguish between centripetal and centrifugal force. Check it out. In each of these events, though, there is only one true force being applied, while the other is only an apparent force. For an externally applied force, the change in velocity depends on the mass of the object. OK, just to be clear, the centripetal force isn’t a single force. If you are inside the car (in a non inertial reference frame), the hanging mass isn’t accelerating. So, in order to make the forces add up to the zero vector there is that fake force pushing to the right. It seems to just make sense.

There is a force which keeps pulling the object towards the centre of … C entripetal ‘s meanings are opposite; centripetal things (1) move or are directed toward a center, (2) operate by means of centripetal force, or (3) tend toward centralization.

Mehn I love these coarse it has greatly improve mY knowledge of studying physics tonight ….but I will like to have a contact with the director and promoters of the website ….here is mY mobile number +2348037575893 …i will be looking forward to here from You …….. “Every object persists in its state of rest or uniform motion (moving) in a straight line unless it is compelled to change that state by forces executed on it.”. Here, maybe these two force diagrams will help. Everything is as it should be. This is a relatively simple concept, but I thought it was so interesting!

3. Go back to the Newton’s 2nd Law equation above. A centrifugal force is a force pointing AWAY from the center of the circle. For the swinging ball, this centripetal force is actually the tension in the string. If there is a constant force on an object, it will have a constant acceleration. where ac is the centripetal acceleration, m is the mass of the object, moving at velocity 'v' along with a path with a radius of curvature (r). What force is pushing it to the side? But it feels something like a sideways gravitational force. 3. Since students have trouble with forces anyway, it seems to be a bad idea to introduce a fake force. In fact, it only works in an inertial reference frame. The magnitude of this fake force depends on the mass of the object and the acceleration of the reference frame. 4 Centrifugal force is not a real force, it is inertia of motion (moving). This is the centrifugal force. In this case, your reference frame would be the cart itself and this reference frame the cart is NOT accelerating. You aren’t ready. Here is a cart with a single constant force. Let’s stick with centripetal and centrifugal with footnotes. The key ingredient is that if there is no net force (total force) acting on an object (if all the external forces cancel each other out) then the object will maintain a constant velocity. (The Calculus can also be used to calculate the velocity experienced by an object subjected to an external force.) 5.

Both centripetal and centrifugal have been derived from Latin.
