Does rolling friction always reduce the net force acting on against an objects motion to zero?

The net force will be zero only if the velocity is constant, which means acceleration is zero.

Does rolling friction reduce the net force acting against an object's motion to zero?
maybe
Rolling friction always reduce the net force acting against an object's motion to zero?
Yes, rolling friction always reduces the net force to zero.
Is it true that rolling friction always reduces the net force acting aginstan objects's motion to zero?
Friction can be reduced, but in most cases there is no practical way to reduce friction to zero.
The force that acts against moving objects is called?
Well, it depends on where and how fast the object is moving. However, forces acting against moving objects would be air resistance (eg. cars or a sky divers), friction (eg. a wheel rolling down a hill), gravity (eg. a ball being thrown into the air)
What is a common unbalanced force acting on objects in motion?
Friction
What is friction acting on objects that are not moving?
Friction is holding immobile objects in place.
Is friction acting on a body which is in pure rolling?
yes there is still alittle friction on a ball that is in pure rolling because there is still interaction between the atoms that contact the surface of the ball and the floor
What acts against the direction of th objects motion?
Any force acting in the direction opposite to motion, such as Friction, wind resistance, or swimming up stream
What friction deals with objects that are already moving?
friction acting on a such a body is called kinetic friction.here friction will try every thing that it can to stop the body.
Why objects moving in fluids must have special shapes?
When objects move through fluids, they have to overcome friction acting on them. In this process they lose energy. Efforts are, therefore, made to minimise friction. So , objects are given special shapes.
What causes a marble to roll?
Because of the force of friction pushing against the ball. The only way it could avoid that is if it wasn't rubbing against the ground and was instead closing floating in air, like the puck in air hockey. The air blowing up on it keeps the puck and the table from rubbing against each other and causing friction. :)
Why does a ball that is rolling come to a stop?
a round object rotates when there is a force acting tangentially.. in this case friction force is acting tangentially... so it should be rolling without stopping.. but it does stop since the weight is not balanced by its normal force(i.e. normal force and weight are not acting on the same point.)
