SUMMARY
The discussion centers on the calculation of work in physics, specifically addressing why work is expressed as Fdcosθ, even in the context of gravitational force. The dot product definition is emphasized, confirming that work is a scalar quantity derived from the force vector and the displacement vector. The equation Fdcosθ is consistently applicable, regardless of the force being gravitational or otherwise, as it represents the component of force in the direction of displacement.
