WebNote: work = F d cos ( θ), where F is the magnitude of the force, d is the magnitude of the displacement, and θ is the angle between the two. Attempt at an answer: My textbook's answer: No the normal force does not cause an object to be displaced, it's perpendicular to the direction of motion. My logic:
WebAboutTranscript. To find the sign of work done, check if the direction of the force and the displacement are the same or not. If they are in the same direction, work is positive, else it's negative. When moved slowly, work done by an external force on a charge is always in the opposite direction of work done by the electric force.

WebWhen a force acts upon an object while it is moving, work is said to have been done upon the object by that force. Work can be positive work if the force is in the direction of the motion and negative work if it is directed against the motion of the object. Work causes objects to gain or lose energy. WebA. Negative net work done on an object always reduces the object's kinetic energy. B. If the work done on an object by a force is zero, then either the force or the displacement must have zero magnitude. C. If a force acts downward, it does negative work. D. The formula W=Fdcosθ can be used only if the force is constant over the distance.
