Linear motion is the most basic of all motions. Uninterrupted objects
will continue to move in a straight line indefinitely. Under every
day circumstances gravity and friction conspire to bring objects
to rest.
Linear motion is measured in two parts. Speed,
and direction. Together these make up the velocity.
Linear motion, is not often used as a starting
point for mechanisms. Click on the links below to find how to convert
