How can one consider a frictional force on a track as constant while frictional forces are non conservative?

This is a very good question. A conservative force is defined as a force that doesn't remove energy from a system. Such forces as a spring force are conservative. However, wherever a frictional force is exerted, heat is produced. It takes energy to make heat, and the energy comes from the kinetic energy of whatever objects have frictional forces exerted upon them. A frictional force will eventually remove all of the kinetic energy from a system. However, a frictional force is constant. The force of friction is defined as the coefficient of friction times mass times the gravitational constant. (The coefficient of friction is represented as the greek letter mu). Regardless of the remaining Kinetic energy in a system, the frictional force will not change, thus a frictional force is constant, but not conservative. Hope this helps whoever asked this question! --An AP PHYSICS STUDENT

What are the examples for non conservative forces?
Non conservative forces are frictional force, air resistance, tension in a string and normal force etc.
Are there any forces when a car goes at a constant speed?
forward thrust from the driving wheels, which is equal ( and opposite ) to the frictional forces from air resistance and rolling resistance ( tyres ) .
2 kinds of forces?
Frictional force and non frictional
What are the conditions for an object to stay at restto keep moving at constant velocityor to move with increasing velocity?
You have three separate situations here:1. Object stays at rest. The force on the object is not great enough to overcome its frictional forces, or its inertia.2. Object keeps moving at constant velocity. The object's inertia and frictional forces are exactly balancedby the Force exerted on it.3. Object moves with increasing velocity (acceleration). The Force on the object exceeds that necessary to overcome its inertia and its frictional forces.
What is something frictional forces cannot do that other forces can?
Most forces other than frictional force can be converted into other kinds of force.
What are consequential forces?
Frictional force

How do forces relate to wear and tear?
Wear and tear comes almost completely from frictional forces.
What forces are involved when a rocket travels through space?
the forces are gravitational force and frictional force.
