Pritish pulls a load up an inclined road. What is/are the force(s) he must overcome to pull it up?
Gravitational Force
Gravitational force is due to earth's gravity, which is always in the downward direction. The force opposing his relative motion along the inclined road is called frictional force, which is an example of contact force. Therefore, he needs to overcome gravitational and frictional force to pull the load up the incline.
