WebApr 8, 2024 · Cross product refers to a binary operation on two vectors in three-dimensional Euclidean vector space. The right-hand rule is used to calculate the cross product of two vectors. The right-hand rule is mainly the result of any two vectors which are perpendicular to the other two vectors. WebExample of cross product usage in physics: A good example is that torque is the cross product of the force vector and the displacement vector from the point at which the axis is (the center of rotation) and the point and which force is applied.
