Physics Class 9 Chapter 6 - Work and Energy

When a force acts on a body and moves it in the direction of the force, what is done? What is the product of force F and displacement S in the direction of force called? What is the formula of work? What are the perpendicular components of Force F? In case when force and displacement are not parallel, then which component causes the body to move on the surface? In case when force and displacement are not parallel, then which component causes the body to move on the surface?
