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.
A body can stay at rest even though forces act on it when the forces acting on the body are balanced, meaning they cancel each other out. This balance of forces results in no net force acting on the body, allowing it to remain at rest.
When a body is at rest, the forces acting on it are balanced. These can include gravitational force pulling the body downward and normal force exerted by the surface supporting the body. As long as these forces are equal and opposite, the body remains at rest.
No, it is not accurate to say that no force acts on a body at rest. Even when a body is at rest, there can still be forces acting on it, such as gravitational forces or normal forces. These forces balance each other out to keep the body stationary.
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.
When a body is falling freely, the only force acting on it is gravity. This force causes the body to accelerate downwards at a rate of 9.81 m/s^2 near the surface of the Earth.

The Law of Inertia states that a body continues in a state of uniform motion unless a force act on it.
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
The force accelerates the body, a=F/m.

An example of force being used to move a stationary object is when you push a door open.
The force acting on an object "A" from outside is action force , and the reaction force is the force exerted by A to the outside object . Therefore, it is obvious that action force and the corresponding reaction force cannot act on one and the same body.
Muscles in the body act as the effort force. When muscles contract, they generate force to move bones and produce movement in the body.
