Question

formula for work done by (1) gravitational force (2) resistive force of air is

Answer 1

work done by any conservative forces are zero
Work Done by Gravity Against Inertia and Air Resistance. When an object is falling freely, the force of gravity is doing work against the resistancefrom inertia and the air resistance ordrag on the object. The forces acting on the object are gravity and the opposite or resistive forces of inertia and air resistanc
