Speed is scalar or vector quantity
WebMar 2, 2024 · Similarly to how speed is the scalar quantity (or magnitude) of velocity, weight is the scalar quantity (or magnitude) of the gravitational force a celestial body exerts on mass. I'm still inclined to think of weight as a vector for convenience and to separate it from everyday language. WebTrue or False 1. A vector is a large quantity and a scalar is a small quantity. 2. A scalar quantity has a magnitude and a vector quantity does not. 3. A vector quantity is described with a direction and a scalar is not. 4. Scalar quantities are path-dependent quantities and vector quantities are not.
