Which formula is used to calculate work done?

The formula for calculating work done is indeed represented by the equation involving force and distance multiplied by the cosine of the angle between the force and the direction of motion. This is because work is defined as the transfer of energy that occurs when a force is applied to an object, causing it to move.

In the specific formula Work = Force x Distance x cos(θ), force represents the magnitude of the applied force, distance is the displacement of the object in the direction of the force, and θ is the angle between the force vector and the direction of displacement. The cosine factor accounts for the direction of the force relative to the movement direction, ensuring that only the portion of the force that acts along the direction of movement contributes to the work done.

When the force is applied at an angle, it is essential to consider only the component of the force that acts in the direction of the displacement to accurately calculate work. If the force is applied in the same direction as the displacement (θ = 0 degrees), then cos(θ) equals 1, and the formula simplifies to work = force x distance. Conversely, if the angle is 90 degrees, indicating that the force is perpendicular to the displacement direction, then no work is done since the cosine of
