What is the formula for calculating work done?

The formula for calculating work done is fundamentally rooted in the relationship between force, distance, and the angle at which the force is applied. The correct formula, which captures this relationship accurately, states that work is equal to the force exerted on an object multiplied by the distance the object moves in the direction of that force, adjusted for the angle between the force and the direction of movement.

When calculating work, if the force is applied in the same direction as the movement, the entire amount of force contributes to the work done. However, if the force is applied at an angle, only the component of the force that acts in the direction of the movement contributes to the work done. This component is represented by the expression cos(θ), where θ is the angle between the force vector and the displacement vector.

This comprehensive formula emphasizes not only the magnitude of the force and distance but also the directional aspects that are essential in understanding mechanical work. Thus, it accounts for scenarios such as inclined planes or forces applied at various angles where not all of the force effectively contributes to the work done on the object.

In contrast, the other options do not adequately capture the influence of direction on work. For instance, while one option states work as Force times Distance, it
