... Just as distance and displacement have distinctly different meanings (despite their similarities), so do speed and velocity. • Speed is how fast something is moving or how much distance is covered in a certain amount of time. There are two types of speed: instantaneous speed, which is an object’s sp ...

Introduction to Circular Motion
... Center of Gravity For a given body, the center of mass is the average position of all the mass that makes up the object. A symmetrical object like a ball can be thought of as having all of its mass concentrated at its geometric center; by contrast, an irregularly shaped object such as a baseball ba ...
