Answer the question in this post to test your concepts for competitive exams.
Circular motion is a very important concept in physics. Here in this page I would like to go through the concept of circular motion. You encounter circular motion in your day to day life. Many rides in amusement parks undergoes circular motion. Curves on highway are part of a circle and cars making a tun undergoes circular motion. Merry-go-Rounds in playgrounds offer further examples of uniform circular motion. Now let us learn more about circular motion.

We already know about electric field and electric potential. We also know that electrostatic field is completely characterized by vector function E(r). The electric field depicts the force exerted on other electrically charged objects by the electrically charged particle the field is surrounding. Now a question arises why do we need introduction of electric potential when we already have electric field for the description of electric force between charges.
