It would cause the object to decelerate.
The backwards force affects a motion by slowing it down
its affect if you push or pull...
increasing mass affects the force of objects in motion because it will slow the object down than its neighbor
If the motion doesn't change, then the net force is zero. If there is a forward force, there must be a counteracting backward force. Quite often, this backward force is friction.
Friction is the force that opposes motion between two objects.
If there is zero net force on an object, the object will not accelerate. (It's velocity will not change.)

Gravity exerts a force on objects; forces change the motion of objects.
Friction is a force that occurs when two surfaces slide past another. The force of friction opposes the motion of an object, causing moving objects losing energy and slow down. When objects move through a fluid, such as air of water, the fluid exerts a frictional force on a moving object.
The motion in a body depends on the the balanced or unbalanced forces acting on it. If the sum of the forces is 0 then it is a balanced force and produces no motion if the sum of the forces isn't 0 then it is unbalanced force. The body will move in the direction in which the force is applied. That's about it
it usually does, but if the force is balanced, it will not change the object's motion
Forces are created in many different ways. . . . . for example strong nuclear force electromagnetic force weak force and gravity
