FAQs on Vertical Circular Motion (Part- 3) Video Lecture - Basic Physics for IIT JAM

1. What is vertical circular motion?
Ans. Vertical circular motion refers to the motion of an object in a circular path in the vertical plane. It involves the object moving in a circular path while also experiencing a gravitational force pulling it towards the center of the circle.
2. What is centripetal force in vertical circular motion?
Ans. In vertical circular motion, the centripetal force is the force that keeps the object moving in a circular path. It acts towards the center of the circle and is provided by a tension force, gravity, or a combination of both depending on the specific situation.
3. How does the speed of an object change in vertical circular motion?
Ans. The speed of an object in vertical circular motion changes throughout the motion. As the object moves upwards, away from the center of the circle, its speed decreases due to the work done against gravity. As the object moves downwards, towards the center of the circle, its speed increases due to the work done by gravity.
4. What is the minimum speed required for an object to complete a vertical loop?
Ans. The minimum speed required for an object to complete a vertical loop is when the object is at the topmost point of the loop. At this point, the object momentarily loses contact with the track and only gravity acts on it. The minimum speed required is calculated using the equation: v = √(rg), where v is the minimum speed, r is the radius of the loop, and g is the acceleration due to gravity.
5. How does the radius of the loop affect the motion of an object in vertical circular motion?
Ans. The radius of the loop affects the motion of an object in vertical circular motion. A smaller radius requires a higher speed to maintain the circular motion, while a larger radius allows for a lower speed. If the radius is too small and the speed is not sufficient, the object will lose contact with the track at the topmost point of the loop.
