If a body is at rest ... or traveling at a constant speed in a straight line ... there
could well be millions of forces acting on it.
The only conclusion you can draw from the fact that it has no acceleration is that
all the forces acting on it must add up to zero.
The force is applied proportional to it...........
Balanced forces cannot bring a body to rest. Balanced forces can act on a body which is already at rest or in motion but equal forces cannot change a bodies acceleration, kinetic energy or momentum.
no force act on it
You could say it if you want, but it's not a true statement. Without investigating the situation in detail, we know immediately that every object on Earth, whether at rest or in motion, is acted upon by a gravitational force directed toward the center of the Earth. There are other exceptions to the statement, but we've already disproven it, utterly and easily.
When the net force acting on the body is zero. The body will remain in equilibrium until an external force is applied to the body.
Gravity, pressure.
The force is applied proportional to it...........
The Law of Inertia states that a body continues in a state of uniform motion unless a force act on it.
Balanced forces cannot bring a body to rest. Balanced forces can act on a body which is already at rest or in motion but equal forces cannot change a bodies acceleration, kinetic energy or momentum.

for every force which act on one body action force there is an equal and opposite forces reaction force which act on same other body
When the net force acting on the body is zero. The body will remain in equilibrium until an external force is applied to the body.
An unbalanced force.
The force accelerates the body, a=F/m.
It can be a force or the absence of a force. A body at rest remains at rest unless it is acted on by a force. But, a body in motion will continue to move at a constant velocity (change its position) unless it is acted by a force.
a force lil' G !!
