Circular motion is just linear motion wrapped around the circumference of a circle. And rotational motion is just like linear motion but it uses angle units instead of length units. First we'll cover the basic and essential parts of motion that we'll use for the rest of the course: position, displacement, velocity and acceleration.

In this paper we establish the existence of a positive solution for an asymptotically linear elliptic problem on . The main difficulties to overcome are the lack of a priori bounds for Palais–Smale sequences and a lack of compactness as the domain is unbounded.
