In each case, does your sketch represent the only possible relative directions of the force and displacement vectors? If so, explain. If not, sketch at least one other possible set of vectors.

Expert Solution & Answer

To determine

The direction of the force exerted on an object and the direction of displacement of an object for different cases.

Explanation of Solution

Introduction:

Work is the measure of energy transferred when a force is applied to move an object through a displacement. Work done by a force acting on an object is equal to the product of the magnitude of the displacement and the component of force parallel to that displacement.

When work done on an object is positive, then the direction of the force exerted on an object and the direction of displacement of an object is the same.

The direction of force and displacement of an object when the work done is positive is shown in figure 1.
