Work done in moving a rock.
How much work does the gravitational field of the earth do on the rock?
i think the gravitational field G needs to be factored in
The work is done by a force when the force displaces the body.

Direction and Work Done by Electric Field
b) By definition, work done by a force is defined as :
Work done = Component of the force in the direction of the displacement x displacement
Or W = FS cosθ where W = Work done, F = Magnitude of force, S = Displacement, θ = Angle between F

Work done by a constant force: Lifting and carrying a pumpkin from a field
Because in horizontal direction there is no force acting (neglect air resistance)
F = 0
therefore,
work done = 0 --Answer
The expert analyzes lifting and carrying a pumpkin from a field.
