Kinetic Energy
Yes, momentum is still conserved even if there is no friction. In the absence of external forces, the total momentum of a system remains constant. Friction only affects the conversion of kinetic energy into other forms of energy, but does not change the overall momentum of the system.
State friction refers to the resistance or difficulty experienced when trying to change or modify an existing system or state. It can relate to various aspects such as organizational inertia, resistance to change, or bureaucratic red tape. State friction often hinders progress and can be a challenge to overcome when implementing new ideas or reforms.
Friction does not "destroy" energy, but rather it transforms some of the mechanical energy into heat energy due to the resistance between two surfaces in contact. This transformation of energy can lead to a loss of usable energy in a system.
Momentum is not conserved when external forces act on a system, such as friction or air resistance, causing a change in the total momentum of the system.
The system with friction is considered closed because it does not exchange energy or matter with its surroundings.
Yes, it can. For instance, if you have friction in the system mechanical energy of the system is not conserved.

The system with friction is considered closed because it does not exchange energy or matter with its surroundings.
Friction in a pulley system mainly occurs where the rope makes contact with the pulley wheels. This friction results in energy loss, reducing the overall efficiency of the system. Lubricants or ball bearings can help minimize this friction and improve efficiency.
In a braking system
To calculate the work done by friction in a system, you can use the formula: Work Force of friction x Distance. First, determine the force of friction acting on the object. Then, multiply this force by the distance the object moves against the frictional force. This will give you the work done by friction in the 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.
The thermal energy formula that accounts for friction in a system is Q Nx, where Q is the thermal energy, is the coefficient of friction, N is the normal force, and x is the distance over which the friction acts.
