Just the 3 basics
It's not necessary to specify that the object is moving at a constant speed. Any object with no outside forces acting on it does that. It also continues moving in a straight line.
Then the result will be the same as if NO forces act on the object (since the sum of the forces is zero). The object will continue moving in a straight line, at constant speed.
Sure. If all of the forces on an object are balanced, then the object continues moving in a straight line at constant speed. All of the forces on an airplane cruising in level flight, or on a car on cruise-control on a straight piece of road, are balanced.

To keep moving in a straight line. This is rather hard to show because the gravitational pull of the Earth is hard to escape without a rocket.
When the entire group of forces acting on an object is balanced, the object's motion is 'uniform' ... its speed is constant and it moves in a straight line. If its speed is changing or its path is not straight, that's called "acceleration", and it means that the group of forces acting on the object is not balanced.
Some Forces do not involve physical contact between the bodies on which they act. -Jauan Williams 3182163642
it moves with uniform velocity ... constant speed in a straight line
Forces that likely act upon a moving object include:frictiongravity
They don't. If there are no external forces acting on a moving object, then the objectcontinues moving in a straight line with constant speed. Whenever an object slows down,it must be the effect of an external force acting on it.
Inertia
Gravith pulls it down; table pushes it up.
