When the box is too heavy or the table too rough.
The object accelerates in the direction of the resultant force.
The frictional force is proportional to the "normal force"; that is, the force pushing the surfaces together, whether that is gravity or anything else.
When the limiting frictional force is greater than the static frictional force, the body will tip about the point before sliding.
it is a mechanical force , so the reactant force on the man is not just the reactive force bt also the frictional force

if the frictional resistance is high, the force will be greater, and if the frictional resistance is low, the force will be smaller.

The mass of the object (force of gravity) and the frictional force of moving the table are greater than the horizontal force that the boy is exerting on the table... so it won't move

The pushing force of the heart is greater in arteries than in veins. The arteries are closer to the heart itself.
If you are behind a car, about to push it forward from a resting position, you will need to exert a force on the car to accelerate it from resting position. While you are pushing against the car, however, there will be a reaction force pushing back at you. In order to produce a large net force against the car without being pushed backward yourself, you need to increase the friction of your feet against the ground...so that the frictional force between your feet and the ground prevents you from sliding backward. The combinations of the frictional force and your force pushing forward against the car will cause the car to move forward. The frictional force of the car being moved from resting position also has to be overcome, of course.
The object floats
static frictional force
i am sure that it is not frictional force.....
