Homework Statement
Suppose there was a planet in deep space. Now drop an object in it's gravitational field. This object has no velocity whatsoever in any direction. Now, would this object start moving straight toward the planet (because that's the direction of net force) or follow a...
So, if an object is moving in a circular path, it has a force constantly directed to the center acting on it, and this force is perpendicular to the velocity. However, imagine now that it's not moving. How can one get this object to move in a circular pathway using centripetal force? Does the...
