Frictional energy is the energy that is transformed into heat when two surfaces rub against each other. It is useful in everyday tasks like walking and driving where friction helps to provide grip and traction. In some cases, frictional energy can be considered wasteful and efforts are made to reduce friction to improve efficiency.
Frictional energy is generated when two surfaces rub against each other, causing resistance to the movement. This resistance leads to the conversion of mechanical energy into heat energy, as some of the energy is lost in overcoming the frictional force.
your question is not clear but fro what i could understand, i can tell you that frictional force always opposes motion of mechanical system ( so it would decrease the system's mechanical energy) therefore i can never increase it.
Frictional forces result in the conversion of mechanical energy into heat energy. This transformation leads to a loss of mechanical energy in the system, causing the principle of mechanical energy conservation to not hold true in these situations.
A frictional force produces thermal energy, often referred to as heat, due to the conversion of mechanical energy into thermal energy during the interaction between surfaces. This heat is a result of the kinetic energy of the interacting objects being transformed into random molecular motion.
No, a catapult works on the principle of stored mechanical energy that is released to propel an object. Frictional force plays a minimal role in the functioning of a catapult as the stored energy is primarily converted into kinetic energy for the launching of the object.

The work done by the frictional force is negative because the force opposes the direction of motion. This means that the frictional force removes mechanical energy from the system by transforming it into heat, resulting in a decrease in the object's kinetic energy.
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.

Inefficiencies in a mechanical device related to parts rubbing together such that kinetic energy is turned into heat energy.
to reduce the energy loss due to frictional force.
Frictional energy can generate heat when objects rub against each other, which can then be used to create electrical energy through methods like thermoelectric conversion. This process involves using temperature differences to produce an electric current by employing materials that generate electricity when heated.
Earthquakes release the energy of frictional stress stored in the Earth's crust by causing the rocks along a fault line to suddenly slip past each other. This sudden movement generates seismic waves that propagate through the Earth, creating the shaking and ground motion associated with earthquakes.
In the case of friction, energy is wasted, i.e., mechanical energy is converted into useless energy, mainly heat.
