Question

use the terms "displacement" and velocity to descibe how uniformly accelearted motion differs from unifrom motion

Answer 1

"Uniform motion" is motion along a straight line with no increase in speed. The velocity is constant in uniform motion.

In uniformaly accelerated motion, there is a constant acceleration is a certain fixed direction. A falling object would be an example. The displacement from the place where motion started is proportional to the square of time.
