1. Work is considered a scalar quantity because it only has magnitude and no direction. It is defined as the dot product of force and displacement vectors, resulting in a single numerical value representing energy transfer, without any associated directional component.

  2. For work to be done on an object, a force must be applied, causing the object to move in the direction of the force. Both the force and the displacement must have a component in the same direction.
