WitrynaFrom a modern physics viewpoint, time is not a vector nor a scalar, it is a coordinate. This is because time is relative depending on the observer, so it cannot be defined as … Witryna21 lis 2024 · What is the difference between a scalar and a vector? A scalar is a quantity that is fully described by a magnitude alone. It is described by just a single number. Some scalar quantities are volume, mass, time etc. A vector is a quantity that is fully described by both a magnitude and a direction. WitrynaYes, torque has units of joules in SI. But it's more accurate and less misleading to call it joules per radian. Let's take the simple case of a single force acting perpendicular to position (reference) vector: τ = r F To tease out energy from this equation, let's consider an infinitesimal change in (rotational) energy d E : d E = τ d θ = r F d θ, two phase synthesis of taxol
