Science Is the momentum of an object moving in a circular path (going at a constant speed) constant? Why or why not? Asked by Dr. John Carmen 13 years ago 1/3/2013 2:41 AM Last updated by anonymous 13 years ago 1/4/2013 10:55 PM
No, it is not constant. Here's why: the momentum depends on velocity and velocity includes direction, which is constantly changing.
