Space | Astro | Cosmo on Instagram: "Circular motion and linear motion are closely related because the movement of an object along a circular path can be described in terms of linear quantities. In linear motion, an object travels a straight distance, whereas in circular motion, the object travels an arc length along the circumference of a circle. This arc length is actually the linear displacement of the object while moving around the circle. The relation between them is that the linear distanc
