FAQs on Circular Motion (Part- 1) Video Lecture - Basic Physics for IIT JAM

1. What is circular motion?
Ans. Circular motion refers to the movement of an object along a circular path. In this type of motion, the object continuously changes its direction while maintaining a constant distance from a fixed point called the center of the circle.
2. What are the types of circular motion?
Ans. There are two types of circular motion: uniform circular motion and non-uniform circular motion. In uniform circular motion, the object moves along a circular path at a constant speed. In non-uniform circular motion, the object's speed or direction changes at different points along the circular path.
3. What is centripetal force?
Ans. Centripetal force is the force that acts towards the center of the circular path, keeping an object in circular motion. It is responsible for continuously changing the direction of the object without altering its speed. The centripetal force is always directed inward and is necessary to prevent the object from moving in a straight line.
4. How is centripetal force related to circular motion?
Ans. Centripetal force is directly related to circular motion as it is the force that keeps an object moving in a circular path. According to Newton's second law of motion, the centripetal force is equal to the mass of the object multiplied by the square of its velocity, divided by the radius of the circular path.
5. What is the difference between centripetal force and centrifugal force?
Ans. Centripetal force is the force that acts towards the center of the circular path, while centrifugal force is the apparent outward force experienced by an object moving in a circular path. Centrifugal force is a reaction force that occurs due to the inertia of the object trying to move in a straight line. It is equal in magnitude but opposite in direction to the centripetal force.
