The same object moves at the speed of V1 for the first time and V2 for the second time on the same plane (V1 > V2). Why is the pulling force the same when the moving speed is different?

This is a high school physics problem, because it is the same plane, so the friction coefficient between the object and the plane is a fixed value, and the friction is equal to the pressure times the friction coefficient. Because it is a uniform motion, the tension is equal to the friction, so even if the speed is different, the tension is the same
