What is rotational motion? Explain it with example. |
Answer» <html><body><p></p>Solution :Here rigid body as a solid metallic or wooden cylinder. <br/> This cylinder shifts from the top of bottom of the inclined plane and thus it has <a href="https://interviewquestions.tuteehub.com/tag/translation-1426133" style="font-weight:bold;" target="_blank" title="Click to know more about TRANSLATION">TRANSLATION</a> motion. <br/> All its particles are not moving with the same velocity at any instant. The particle <a href="https://interviewquestions.tuteehub.com/tag/near-1112277" style="font-weight:bold;" target="_blank" title="Click to know more about NEAR">NEAR</a> from the axis of cylinder has less velocity and particles for <a href="https://interviewquestions.tuteehub.com/tag/away-386546" style="font-weight:bold;" target="_blank" title="Click to know more about AWAY">AWAY</a> from the axis of cylinder has more velocity. <br/> Such type of cylinder velocity is not pure translation it has combined velocity of rotation with it. <br/> The line along which the body is fixed is termed as its axis of rotation, its motion known as rotational motion. <br/> If all the paticles motion of a rigid body move along circular <a href="https://interviewquestions.tuteehub.com/tag/path-11833" style="font-weight:bold;" target="_blank" title="Click to know more about PATH">PATH</a> and the centre of all these circles fall on a definite straight line then the motion of the body is called rotational motion. <br/> If all the particles of a rigid body perform circular motion and the <a href="https://interviewquestions.tuteehub.com/tag/centres-912272" style="font-weight:bold;" target="_blank" title="Click to know more about CENTRES">CENTRES</a> of these circles are steady on a definate straight line called axis of rotation. <br/> Examples of rotation motion : A ceiling fan, a potter.s wheel, a giant wheel in a fair, a marry-go-round etc.</body></html> | |
