What is the difference betweencentripetal acceleration and centrifugalforce? |
|
Answer» Centripetal acceleration is a name given to the type of acceleration that causes the velocity of an object to change in a way such that it starts moving in a circular path. When the object is moving in circular path, the centripetal acceleration is directed from the object to the circle's centre (perpendicular to velocity). This is caused by a centripetal force that acts towards the centre of a circle. Centripetal force is a real force (it can be tension in string, gravitational, electrostatic, etc). centrifugal force is a fictitious force. It doesn't really exist. We use the concept of centrifugal force to describe the motion of objects in a rotating frame of reference Centrifugal force: Imagine a circular ride in which a child sits on a horse and moves in a circle. We know that the rod holding the horse exerts a centripetal force to keep the horse moving in a circle, i.e. pulling force towards the centre of the circle. |
