rotational motion problems

Comparison of Linear and Rotational Motion - When a rigid body such as a merry-go-round rotates around an axis, each particle in the body moves in its own circle around that axis. Since the body is rigid, all particles make one revolution in the same amount of time. i...

When a rigid body such as a merry-go-round rotates around an axis, each particle in the body moves in its own circle around that axis. Since the body is rigid, all particles make one revolution in the same amount of time. i.e., they all have the same angular speed w..

Consider a pulley fixed at a typical Indian well on which a rope is wound with one end attached to the bucket. When the bucket is released, the pulley starts rotating. As the bucket goes down, the pulley rotates more rapidly till the bucket goes into the wate..

Projectile Motion - Projectile motion is an example of curved motion with constant acceleration. This is the two dimensional motion of a particle thrown obliquely into the air. The ideal motion of a cricket ball, a golf ball or a bullet is an exampl..

Introduction - Circular Motion - Circular motion is commonly seen in both microscopic and large systems. Motion of the electron, planetary motion and rotation of tyres are common examples of circular motion. What is circular motion..

Circular motion is commonly seen in both microscopic and large systems. Motion of the electron, planetary motion and rotation of tyres are common examples of circular motion. What is circular motion? It is a type of motion ..

In a lawn sprinkler when water sprays out of the nozzles, a backward force is exerted on the nozzle as a result of which it starts rotating. Consequently, water is sprayed in all directions. Consider a block of weight w resting on a horizontal surface. The block exerts a downward for..

Consider a body of mass 'm' tied to a string and rotated in a vertical circle of radius 'r'. The velocity (speed) of the body keeps changing. It is maximum at the bottom and a minimum at the to..
