What to do with circular motion ... keep the length of the string constant. Now for a force diagram of the stopper at the instant shown. The net force on the mass is not the zero vector, this ...

one of the biggest ideas is that a force changes the motion of an object. One way to mathematically write this is with Newton's second law: If a net force acts on an object, it accelerates.

Learn the key differences between centripetal and centrifugal forces, their real-world applications in physics, and how they shape our understanding of circular motion. When you purchase through ...
