WebWork is not the same thing as force, which is a vector quantity, because work is the result of force. Why is work done a scalar? Work is a scalar quantity because it is the dot product of two vectors (Force and displacement). Dot product of two vectors becomes scalar quantity. So, work done has only magnitude but not direction. 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.

WebJul 11, 2024 · Force, like displacement, velocity, and acceleration, is a vector quantity, which is why Newton’s Second Law is written as sigmaF = ma. Put into words, it says that the vector sum of the forces acting on an object is equal to its mass (a scalar) multiplied by its acceleration (a vector). Is force a vector explain?
