Initially, the wheel has an angular momentum in the upward direction. When the person turns over the wheel, the angular momentum of the wheel reverses direction. Because the person-wheel-chair system is an isolated system, total angular momentum must be conserved, and the person begins to rotate in an opposite direction as the wheel. The vector sum of angular momentum in a) and b) is the same, and momentum is conserved. This example is quite counterintuitive. It seems odd that simply moving a bicycle wheel would cause one to rotate. However, when observed from the standpoint of conservation of momentum, the phenomena makes sense.

sir what is the difference between intertia and moment of inertia?
@mohdt786
10 жыл бұрын
Sir, in the example of a cycle, the wheel rotates even when we don't paddle because of moment of inertia in which we need to increase the radius so it keeps rotating. But if we take the same example with angular momentum, why should the radius be decreased so that the rotation (angular velocity) is increased ???

SIR DIRECTION OF ANGULAR DISPLACEMENT IS ALWAYS PERPENDICULAR TO THE PLANE OF ROTATION BUT IAM NOT GETTING HOW. I KNOW RIGHT HAND SCREW RULE BUT I DONT UNDERSTAND HOW IT HOLDS I MEAN IF YOU LOOK AT ANY PARTICLE PERFORMING CIRCULAR MOTION ITS DISPLACEMENT IS ALWAYS ALONG THE CIRCUMFERENCE OF THE CIRCLE i.e IN THE PLANE OF MOTION SO how ANGULAR DISPLACEMENT CAN BE PERPENDICULAR HOW CAN I IMAGIN THE DIRECTION OF ANGULAR DISPLACEMENT PERPENDICULAR TO PLANE WHEN MOTION IS IN THE PLANE? I AM HAVING THIS CONCEPTUAL DOUBT WHICH NEEDS TO BE CLARIFIED OTHER WISE I WILL NOT UNDERSTAND THIS COMPLETE CHAPTER .PLEASE SIR CLARIFY THIS .
