Question

If a bulldozer pushes a boulder, which force is exerted on the boulder?

Answer 1

Answer:

Mechanical Force (due to the pushing of the bulldozer and the bulldozer getting pushed back (Newton's third law)).

Gravitational Force (due to the force of gravity of the Earth).

Frictional Force (due to the moving of the boulder and its being in contact of the ground while being pushed) (also the friction between the bulldozer and the boulder).
