10 Questions
What are the two types of circular motion mentioned in the text?
Revolution and rotation
Why is circular motion considered accelerated?
Direction of velocity changes at every instant
What makes circular motion periodic?
Particle repeats its path along the same trajectory
How is angular displacement analogous to displacement in translational motion?
Angular displacement is similar to displacement in translational motion
What is the formula for tangential velocity in circular motion?
Tangential velocity = angular velocity x radius
What is Uniform Circular Motion (UCM)?
Circular motion where the speed of the particle remains constant, and only the direction of velocity changes at every instant.
How can the direction of angular velocity be determined?
By using the right hand rule, where the thumb points in the direction of angular velocity.
What is the centripetal force in Circular Motion?
The force directed towards the center of the circular path, responsible for keeping an object in circular motion.
What are the forces acting on a car on a horizontal circular track?
Weight mg downwards and normal reaction N upwards.
What are the forces acting on a point mass undergoing vertical circular motion under gravity?
Weight mg downwards and tension along the string.
