When the object is at rest, the acceleration is zero. so the net total force acting on the body from all directions should be zero. when the object is moving with constant velocity, the acceleration is zero, so in this case too, after the motion is started, the force on the body should be zero. when the velocity is increasing, some acceleration is present, so some force should be present in the direction of the motion.
These are the various cases which can be explained by the equation:
Force = Mass * Acceleration.
here the mass remains constant, so acceleration depends on the net force
Inertia.
Newtons first law states that objects in motion stay in motion unless acted upon by an outside force.
The mass of the body. The same thing is usually referred to as inertia, which is the relunctance of the body to acceleration.

inertia
Objects moving in uniform circular motion will have a constant speed, and two objects with the same acceleration have a constant velocity.
It isn't. Constant velocity? Uniform velocity across a group of objects?
A change in an objects velocity is called acceleration. Velocity is defined as an objects speed of travel AND its direction of travel. Acceleration can change only an objects speed, only its direction or both. If there is no acceleration acting on the object, then the velocity remains constant.
An object in motion.
Objects moving at constant speed in a straight line are said to be in equilibrium. That is there is no force acting on them. If a force was acting there would be aceleration and the velocity would change.

The normal tendency of objects - when no force acts on them - is to move in a straight line, at a constant speed and direction (that is, a constant velocity). However, when there is a force, an object's velocity may be changed. That's what happens to the Moon, as well as to other objects in some orbit. In this case, the force is provided by gravitational attraction from Earth.
A change in an objects velocity is called acceleration. Velocity is defined as an objects speed of travel AND its direction of travel. Acceleration can change only an objects speed, only its direction or both. If there is no acceleration acting on the object, then the velocity remains constant.
Objects would move with constant velocity or stay at rest.
The first law comes closest. Objects have a tendency not to change their velocity.
When acceleration is zero, then the object is moving in a straight line with constant speed. (That's the effective meaning of constant velocity.)

An object in motion.
When all forces are balanced, the object can either be moving at a constant velocity or be at rest. But because you asked for balanced forces on a moving object, it is moving at a constant velocity.
Inertia is the tendency for an object in motion to stay in motion. What you are referring to is momentum which is affected by mass and velocity.
