Speed is the distance traveled divided by the time of travel. For example; if you were to travel a distance of 10 miles in 2 hours time, then your average speed equals 5 miles per hour. s=d/t (s=speed, d=distance, t=time, and the / means to divide). The word velocity is very similar to speed (except velocity also has a direction called a vector) and in most cases we will now use the letter "v.

Center of gravity; and Rotational variables 10-25-99 Sections 7.8 – 8.3 Center of gravity. The center of gravity of an object is the point you can suspend the object from without there being any rotation because of the force of gravity, no matter how the object is oriented.

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time.Velocity is equivalent to a specification of an object’s speed and direction of motion (e.g. 60 km/h to the north). Velocity is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of bodies.
