What dose friction do to an object that is moving

To determine the force needed to maintain a constant velocity, we need to understand the concept of equilibrium. When an object is moving at a constant velocity, the net force acting on it is zero. In this case, the force of friction on the sliding object is opposing its motion. Therefore, to maintain a constant velocity, the force needed should be equal in magnitude and opposite in direction to the force of friction.

In this scenario, since the force of friction is 25 N, the force needed to maintain a constant velocity would also be 25 N. This force would need to be applied in the direction opposite to the force of friction. By applying the force of 25 N in the opposite direction, it will cancel out the force of friction, resulting in a net force of zero and allowing the object to continue moving at a constant velocity.
