Ch#2 | Force and Motion | Vector or Cross Products | Physics Class 11 | New Syllabus

Описание: This video covers the topic of vector or cross products in detail. It begins with an introduction to the cross product, followed by the definition of the normal unit vector using a tangible plane. The right-hand rule for determining the direction of the cross product is explained practically. Next, the characteristics of the vector product are discussed, particularly for unit vectors i, j, and k. A key property is highlighted—that the magnitude of A × B equals the area of the parallelogram. Finally, two practical examples are given: torque as the product of moment arm and force, and the magnetic force on a charge moving in a uniform magnetic field.
