FAQs on Circular Motion (Part- 2) 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, where the object continuously changes its direction but remains at a constant distance from a fixed center.
2. What is the centripetal force in circular motion?
Ans. The centripetal force is the force that acts towards the center of the circular path and keeps an object moving in a circle. It is responsible for continuously changing the object's direction and preventing it from moving in a straight line.
3. How is centripetal force related to circular motion?
Ans. Centripetal force is directly related to circular motion as it provides the necessary force to keep an object moving in a circular path. Without a centripetal force, the object would move in a straight line tangent to the circle.
4. What is the difference between centripetal force and centrifugal force?
Ans. Centripetal force is the inward force acting towards the center of the circle, responsible for keeping an object in circular motion. On the other hand, centrifugal force is the apparent outward force experienced by an object moving in a circular path, which is actually a result of inertia.
5. What are some real-life examples of circular motion?
Ans. Some examples of circular motion in real life include the Moon orbiting around the Earth, a car taking a turn on a curved road, a spinning top, a swinging pendulum, and a satellite orbiting around a planet.
