WebForce and displacement are both vector quantities, but we know that the scalar or dot product of two vector quantities results in a scalar quantity. Thus, Work done is a scalar quantity. Work Formula Derivation. Work done by an external force is equal to the change in kinetic energy of the object. i.e. $W = \Delta K$ $W = {K_f} – {K_t}$ WebVectors are orthogonal if they are perpendicular to each other meaning the dot product of the two vectors is zero. ...

WebThe dot product appears all over physics: some field (electric, gravitational) is pulling on some particle. We'd love to multiply, and we could if everything were lined up. But that's never the case, so we take the dot product to account for potential differences in direction. WebDec 8, 2024 · The exterior product of two vectors is a bivector, whose directions are very natural (while torque as a vector is at right angles to the force and the lever arm, in exterior product it's simply a bivector defined by two directions -- the force and the leve arm). Unfortunately, exterior products are difficult to teach early on.
