Mastering Linear Motion

Linear motion, also called rectilinear motion, is one-dimensional motion along a straight line, and can therefore be described mathematically using only one spatial dimension.

The two types of linear motion are uniform linear motion, with constant velocity (zero acceleration), and non-uniform linear motion, with variable velocity (non-zero acceleration).

Newton's first law of motion states that objects that do not experience any net force will continue to move in a straight line with a constant velocity until they are subjected to a net force.
