Forces that likely act upon a moving object include:frictiongravity
Friction is speed's worst enemy. If no forces act on an object, it is stationary. If a force acts on an object, it keeps going forever until another force acts on it (such as friction!!!).
That depends. If no forces act on the object, it will. If forces do act on the objects, such forces may change the object's velocity.
If the object doesn't move, the forces HAVE TO be balanced. There is no other way.
If forces on an object are balanced, the object will not accelerate - i.e., its velocity won't change.

If forces on an object are balanced, the object will not accelerate - i.e., its velocity won't change.
Then the object will not accelerate (if it is stationary, then it will remain stationary, if it is already moving it will continue to move at the same velocity until a force begins to act on it).
a larger object
An object experiencing balanced forces is said to be in equilibrium. Thus, unless an outside force acts upon the object, it will remain either stationary or at constant speed, it will not accelerate.
Because NOT all forces are equal and opposite. By Newton's Third Law, if object A attracts object B, then object B also attracts object A - with an equal but opposite force. But those forces act on DIFFERENT objects! The forces on object A, and on object B, may be unbalanced!Because NOT all forces are equal and opposite.

If forces on an object are unbalanced, the object will accelerate or decelerate. If forces on an object are balanced, the object will stay still or keep moving with the same velocity.
That's it. A force is a push or pull on an object.
