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 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.

WebCentripetal Force Because an object in uniform circular motion undergoes acceleration (by changing the direction of motion but not the speed), we know from Newton’s second law of motion that there must be a net external force acting on the object. WebASK AN EXPERT. Science Physics The escape velocity is defined to be the minimum speed with which an object of mass m must move to escape from the gravitational attraction of a much larger body, such as a planet of total mass M. The escape velocity is a function of the distance of the object from the center of the planet R, but unless otherwise ...

WebCentripetal force is defined as the force towards the center of an instantaneous circle of a given curve at each point (even if the curve is not a circle itself).
