... In our study of motion, we need to start clarifying the concept of mass. In effect, we will find that mass is a measure of how hard it is to get an object moving. Applying a force to a light object will get the object into significant motion. Applying that same force to a heavy object will only seem ...

... If we tie a mass to a string and swing the mass around in a circle, some force is required to keep the mass from flying off in a straight line This is a centripetal force, a force directed towards the center of the system The tension in the string provides this force. Newton determined that this for ...
