Can a centripetal force do work on an object
WebANSWER: The centripetal force is always perpendicular to the direction of motion. Only the component of the force in the direction of motion can do work. The centripetal force has no such component, so it can never do … WebFor an object moving in a circular path, the centripetal force acts on it towards the centre of the path. Q. Examine these two statements and and select the answer: Statement I : A body moving in a circular path is acted upon by the centripetal force.

WebAug 11, 2024 · By substituting the expressions for centripetal acceleration a c ( a c = v 2 r; a c = r ω 2 ), we get two expressions for the centripetal force F c in terms of mass, velocity, angular velocity, and radius of curvature: (7.6.4) F c = m v 2 r; F c = m r ω 2. You may use whichever expression for centripetal force is more convenient. WebSep 17, 2024 · What happens to the velocity of an object if the centripetal force is increased? The force can indeed accelerate the object – by changing its direction – but it cannot change its speed. In fact, whenever the unbalanced centripetal force acts perpendicular to the direction of motion, the speed of the object will remain constant.
WebExpert Answer. 100% (4 ratings) Here, in the given question we have to explain about work done by a centripatal force. As we know that, Centripetal force is the force due to … WebNo the normal force does not cause an object to be displaced, it's perpendicular to the direction of motion. My logic: But what if the displacement is in a vertical direction, so now the normal force with is at either 0 degrees or 180 degrees? For example, in an elevator if it is accelerating upwards doesn't the normal force do work?
WebDoes the centripetal force acting on an object do work on the object? a. No, because the force and the displacement of the object are perpendicular. b. Yes, since it takes energy... WebAn object is in a uniform circular motion. Does the centripetal force do work on the object? (A) Yes, since the object moves, and work is force times distance. (B) Yes, since it takes energy to turn an object. (C) No, because the object has constant speed. (D) No, because the object's displacement is zero. (E) No, because the centripetal force is
WebAny net force causing uniform circular motion is called a centripetal force. The direction of a centripetal force is toward the center of curvature, the same as the direction of …
