🔴 TORQUE - Derivation || Rotational Motion - Part 02 || in HINDI

In this Physics video lecture in Hindi for class 11, class 12 and IIT JEE we derived the expression for torque. We found that torque is the cross product of position vector of the point where the force is being applied from the axis of rotation. Torque about the axis of rotation is the product of the force applied and the perpendicular distance of the point of application of the force from the axis. Initially, it seems that force is responsible for rotation of a body, but it is not true. Sometimes, esp. when force is applied through the axis of rotation, it does not produce any rotational motion but translational motion. So we needed to introduce a new term called torque. ★★★★★★★★★★★★★★★★ Click to visit the homepage of our channel :    / @edupoint.physics   Arijit Daripa EduPoint, Dam Road, Chandil, Dist- Seraikela-Kharsawan, Jharkhand, India.
