Uniform Circular Motion
... Other forms, such as 4! 2 R 2 f / T or 2! R" f , while valid, are uncommon. Often we decide which expression to use based on information that describes the orbit. A convenient measure might be the orbit’s radius. We may also independently know the period, or the frequency, or the angular velocity, o ...

Newton`s First Law
... Newton’s First Law of Motion • Definition: An object in motion stays in motion, or an object at rest stays at rest until an unbalanced net force acts on it. • Under these conditions the first law says that if an object is not pushed or pulled upon, its velocity will naturally remain constant. This ...

Speed & Velocity
... The unit of speed is the meter per second (m/s). Because speed has magnitude only, it scalar quantity. Velocity on the other hand is a vector because it is defined by magnitude and direction thus: Velocity is the distance moved in a defined direction per unit time. ...
