Give some examples of motion.

(N/A) Motion is common to everything in the universe. We walk,run,and ride a bicycle. Even when we are sleeping,air moves into and out of our lungs,and blood flows in arteries and veins. We see leaves falling from trees and water flowing down a dam. Automobiles and planes carry people from one place to another. The Earth rotates once every $24$ hours and revolves around the Sun once in a year. The Sun itself is in motion in the Milky Way,which is again moving within its local group of galaxies.
