TRUE OR FALSE a object going in a circular path with constant speed encounters n

Question

TRUE OR FALSE a object going in a circular path with constant speed encounters no external interaction because constant speed indicates the location at regular and equal time intervals is equally spaced TRUE OR FALSE a object going in a circular path with constant speed encounters no external interaction because constant speed indicates the location at regular and equal time intervals is equally spaced TRUE OR FALSE a object going in a circular path with constant speed encounters no external interaction because constant speed indicates the location at regular and equal time intervals is equally spaced

Explanation / Answer

True

when no work is done upon an object by external forces, the total mechanical energy (potential energy plus kinetic energy) of the object remains constant. So if an object is moving in a horizontal circle at constant speed, the centripetal force does not do work and cannot alter the total mechanical energy of the object. For this reason, the kinetic energy and therefore, the speed of the object will remain constant. The force can indeed accelerate the object - by changing its direction - but it cannot change its speed
