Coupled Systems & Pulleys
It is possible for objects to share similar motions with other objects, an example would be a car and the driver, both are traveling at the same speed and direction. When scenarios like this occur, we call it a coupled system. This section will help develop the necessary tools to identify coupled systems and the resulting constraints that arise from this coupling.
Forces & Uniform Circular Motion
Objects traveling in a circle at a constant speed are considered to be in uniform circular motion (UCM). Recall velocity has both magnitude and direction, so even though the magnitude of the tangential velocity remains the same in UCM, the direction is constantly changing. For this special case of motion the acceleration points towards the center of the circle which means the net force does as well.
