Linear Velocity

Linear velocity, abbreviated as v, is the rate of change of an object's linear position with respect to time.  It is a vector quantity that has both magnitude and direction.  In simpler terms, linear velocity tells you how fast an object is moving in a straight line and in which direction.  It's important to note that linear velocity is different from angular velocity.  Linear velocity is concerned with the motion along a straight path, while angular velocity deals with the rate of rotation around an axis.

 

Linear Velocity Formula
\( v = r \; \omega  \)     (Linear Velocity) \( r =  v \;/\; \omega \) \( \omega =  v \;/\; r \)
Symbol	English	Metric
\( v  \) = Linear Velocity	\(ft\;/\;sec\)	\(m\;/\;s\)
\( r  \) = Circular Path Radius	\(deg\)	\(rad\)
\( \omega \)   (Greek symbol omega) = Angular Velocity	\(deg\;/\;sec\)	\(rad\;/\;s\)
