Question

Minakshee wants to displace a wooden block from point A to point B along the surface of a table. She has used force F for the purpose. Has all the energy she spent been used to produce acceleration in the block? Which forces have been overcome using that energy?

Answer 1

Explanation:

The slope of the table provides a mechanical advantage as a simple machine. The vertical force of gravity acting on it is spilt into two smaller forces,one perpendicular to the plane and one parallel.

Only the force which is parallel is capable to overcome or counter by pushing ignoring friction by Minakshee.

I hope it helps.
