Friction is not a conservative force because it depends on the path taken by an object, not just its initial and final positions. The work done by friction is always negative and results in energy being dissipated as heat, making it non-conservative. Additionally, the force of friction is not only determined by the relative positions of objects, but also by factors such as surface roughness and the nature of the materials in contact.

Why frictional force is known as non conservative force?
Frictional force is known as a non-conservative force because it depends on the path taken by an object and not just on the initial and final positions. Work done against friction to overcome it does not depend solely on the initial and final positions, making it non-conservative. Energy is dissipated as heat in overcoming friction, leading to a loss of mechanical energy.
What are the examples of non conservative forces?
Examples of non-conservative forces include friction, air resistance, tension in a moving rope, and drag force in fluids. These forces do work that depends on the path taken, leading to a loss of mechanical energy in a system.
Which of the following is considered to be a conservative force?
Air resistance
Is the electric force a conservative force?
Yes, the electric force is a conservative force.
What does the friction force vs normal force graph reveal about the relationship between friction force and normal force?
The friction force vs normal force graph shows that there is a direct relationship between the friction force and the normal force. As the normal force increases, the friction force also increases. This indicates that the friction force is proportional to the normal force.

What is friction and what does it produce?
Friction produces heat!!!!!

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.

Is the electric force a conservative force?
Yes, the electric force is a conservative force.
What does the friction force vs normal force graph reveal about the relationship between friction force and normal force?
The friction force vs normal force graph shows that there is a direct relationship between the friction force and the normal force. As the normal force increases, the friction force also increases. This indicates that the friction force is proportional to the normal force.
How to find the friction coefficient in a given system?
To find the friction coefficient in a given system, you can use the formula: Friction coefficient Force of friction / Normal force. The force of friction is the force resisting the motion of an object, and the normal force is the force exerted perpendicular to the surface the object is on. By dividing the force of friction by the normal force, you can calculate the friction coefficient.
What is the difference between non-conservative and conservative forces in the context of physics?
In physics, non-conservative forces cause a change in an object's total mechanical energy, such as friction or air resistance. Conservative forces, like gravity or spring force, do not change the total mechanical energy of an object.
Which is the larger the kinetic friction force or the statical friction force?
Statical friction
What does the friction vs normal force graph reveal about the relationship between friction and the normal force?
The friction vs normal force graph shows that there is a direct relationship between friction and the normal force. As the normal force increases, the friction force also increases. This indicates that the friction force is dependent on the normal force acting on an object.
What is the effect of force on friction?
The force acting on an object increases the friction between the object and the surface it is on. As the force increases, the friction force also increases proportionally until it reaches a maximum value, called the limiting friction. This relationship is described by the equation: friction force = coefficient of friction * normal force.
