Centripetal Acceleration. So far, we have learned that for an object to move in uniform circular motion, it must be subject to a centripetal force. Since the object experiences a …
ادامه مطلبFurthermore, because the block is traveling along a circular path while in the loop, it will experience a centripetal force. At the top of the loop, the centripetal force will be due to a combination of the weight of the block as well as the normal force. We're looking for a starting height that will just allow the block to travel around the loop.

In order to do that, we start by reviewing the basic equation for average linear acceleration: Now l et's look at an object moving at a constant angular velocity. Because the object has a constant
ادامه مطلبWell, objects that are moving in a circle are acting under a centripetal force. What's more, the person in that rotating frame sees everything being under a centrifugal force, so the centripetal force has to not only be large enough to make the object move in a circle, it has to counteract the centrifugal force.
ادامه مطلبThe speed of the object at point A is v 1 and the speed of the object at point B is v 2.Keep in mind though that this is a uniform circular motion, so the speed is constant. In other words, v 1 = v 2. The only thing that changed is the direction.
ادامه مطلبTo understand acceleration, let us take a numerical example. An object starts from rest and picks up speed such that its velocity becomes 5 m/s in 10 seconds. It took 10 s to go from 0 m/s to 5 m/s. Then, the rate at which its velocity changed is: (5 m/s – 0)/10 s = 0.5 m/s 2. Therefore, its acceleration is 0.5 m/s 2. Examples
