A couple acting on a body is a pair of equal and opposite forces that do not have a resultant force but do produce a turning effect or moment on the body. This can cause the body to rotate around its center of mass.
A body in uniform motion has no net force acting on it. That means that either there are no forces at all, or else that all the forces acting on it add up to zero.
When forces acting on a body are unbalanced, the body will experience acceleration in the direction of the net force. This acceleration causes the body to change its velocity, resulting in motion. The body will continue to accelerate until the forces acting upon it become balanced.
When a body is fully or partially immersed in a liquid, the force acting on the body is buoyancy, which is directed upwards and is equal to the weight of the liquid displaced by the submerged part of the body.
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.
A rigid body will remain in equilibrium when acted upon by a non-parallel coplanar force if the vector sum of all forces acting on the body is zero, and the vector sum of all torques (or moments) acting on the body is also zero. This condition is known as the equilibrium of forces and moments.
Yes, a force acting perpendicular to a horizontal force on a body can cancel out the horizontal force if the two forces are equal in magnitude and opposite in direction. This is known as the equilibrium condition, where the net force acting on the body is zero.
The nervous system is the fast-acting control system.

The body accelerates.
The slow acting control system of the body is the Endocrine system. It is responsible for producing and releasing hormones into the blood.
When a body is fully or partially immersed in a liquid, the force acting on the body is buoyancy, which is directed upwards and is equal to the weight of the liquid displaced by the submerged part of the body.
force acting on unit mass of body is the acceleration of that body.

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.
"The condition of equilibrium or motion of a rigid body is remain unchanged, if a force acting on the rigid body is replaced by another force of the same magnitude and same direction but, acting anywhere along the same line of action."
to me it is a form of acting, your telling a story through your body instead of through words
