Question

I don't want unnecessary answers..........

Please help me to find answer for this question pleaseeeeeee

if you trying to push a heavy box on a horizontal surface, list various forces acting on the box. State the condition under which this box will start sliding on the surface. How will the magnitude of applied force required to move the box change if:
(a) weight of the box is increased?
(b) the surface on which the box is placed is more rough?

Answer 1

Frictional force,Muscular force, Gravitational force
The box will start sliding on the surface if we make the surface smooth and we can also use a wheel to slide the box easily.
I think the magnitude of applied force can be changed by making the surface more rough(b).

Sorry I don't know anymore.

Answer 2

forces are always act in pairs.
The forces acting on it are:-
*frictional force
*gravitational force

*your force which you are applied
*force act as a reaction againt gravity
The object starts sliding when your applied force are more than frictional force applied by ground.
(a)force is directly proportional to the weight of body.when weight increased ,we must apply more force .
(b)if the surface is rough this means to more frictional force applied by surface.as a result to overcome from friction we must applied enough force
