## FAQs on Circular Motion Video Lecture - Physics for Airmen Group X - Airforce X Y / Indian Navy SSR

 1. What is circular motion?
Ans. Circular motion refers to the movement of an object along a circular path, where its distance from a fixed point remains constant. It involves continuous change in direction but not in speed, resulting in the object's motion around a central point.
 2. What are some real-life examples of circular motion?
Ans. Some real-life examples of circular motion include a revolving ceiling fan, a spinning top, a car moving around a roundabout, the Moon orbiting around the Earth, and the Earth revolving around the Sun.
 3. What is centripetal force in circular motion?
Ans. Centripetal force is the force that keeps an object moving in a circular path. It always acts towards the center of the circle and is responsible for continuously changing the direction of the object's velocity vector without changing its speed. It is necessary to maintain circular motion.
 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. Without centripetal force, an object would move in a straight line tangent to the circle instead of following the curved path. It acts as the inward force required to maintain the object's curved trajectory.
 5. How does the speed of an object affect circular motion?
Ans. The speed of an object affects circular motion by determining the magnitude of the centripetal force required to keep it in the circular path. Higher speeds require larger centripetal forces, while lower speeds require smaller centripetal forces. If the speed becomes too low, the object may fail to complete the circular path and fall towards the center.
