Rotation Motion, Moment Of Inertia, IIT-JEE/NEET #neet #jeemains #momentofinertia #rotationalmotion
In this live Lecture I'll discuss Rotation Motion for JEE Mains and NEET.
Rotation or rotational motion is the circular movement of an object around a central line, known as axis of rotation. A plane figure can rotate in either a clockwise or counterclockwise sense around a perpendicular axis intersecting anywhere inside or outside the figure at a center of rotation.
घूर्णन या घूर्ण गति एक केन्द्रीय रेखा के परितः किसी वस्तु की वृत्तीय गति है। एक समतल आकृति एक लम्बवत् अक्ष के परितः दक्षिणावर्त या वामावर्त दिशा में घूम सकती है, जो घूर्णन के केन्द्र पर आकृति के अन्दर या बाहर कहीं भी प्रतिच्छेद करती है।
moment of inertia, in physics, quantitative measure of the rotational inertia of a body—i.e., the opposition that the body exhibits to having its speed of rotation about an axis altered by the application of a torque (turning force). The axis may be internal or external and may or may not be fixed.
The theorem of parallel axis states that the moment of inertia of a body about an axis parallel to an axis passing through the centre of mass is equal to the sum of the moment of inertia of body about an axis passing through centre of mass and product of mass and square of the distance between the two axes.
The parallel axis theorem, also known as Huygens–Steiner theorem, or just as Steiner's theorem, named after Christiaan Huygens and Jakob Steiner, can be used to determine the moment of inertia or the .
गति विज्ञान में समान्तर अक्ष का प्रमेय या स्टीनर का प्रमेय जड़त्वाघूर्ण से सम्बन्धित एक प्रमेय है। यदि किसी पिण्ड के द्रव्यमान केन्द्र से जाने वाली किसी अक्ष के सापेक्ष उस पिण्ड का जड़त्वाघूर्ण ज्ञात हो तो इस प्रमेय की सहायता से इस अक्ष के समान्तर किसी भी अक्ष के सापेक्ष उस पिण्ड का जड़त्वाघूर्ण निकाला जा सकता है।
This theorem states that the moment of inertia of a planar body about an axis perpendicular to its plane is equal to the sum of its moments of inertia about two perpendicular axes concurrent with the perpendicular axis and lying in the plane of the body.
