Force and displacement are combined to form the formula for work. Work is a scalar quantity as a result. Hence, Work is a scalar. Suggest Corrections 60 Similar questions Q. Is work a scalar or a vector quantity. Q. Is work done a scalar or vector quantity? Q. Is work a scalar ...
Describing a Force: A force is avector quantity. A vector quantity is a quantity which has both magnitude and direction. To fully describe the force acting upon an object, you must describe both its magnitude and direction. Thus, 10 Newtons of force is not a complete description of the for...
