rigid motions

Introduction - Physicists love to look at something complicated and find in it, something simple and familiar. Here is an example. If you flip a baseball bat into the air, its motion as it turns, is clearly more complicated than that of a non-spinning tossed ball, which moves like a parti..

Summary - The centre of mass is an imaginary point where one can assume the entire mass of the given system or object to be positioned. Principle of conservation of linear momentum states that the linear momentum of a system remains constant if the external forces acting on the system add up to zer..

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..

Rigid Body Rotation and Equation of Rotation of Motion - 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 rapid..

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...

Motion of Particles and Rigid Body..

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 . ..
