Respuesta :
The friction force applied to the block performs nonconservative work
on the system.
What is Friction force?
- The force preventing sliding against one another of solid surfaces, fluid layers, and material components is known as friction.
- There are various kinds of friction: Two solid surfaces in contact are opposed to one another's a relative lateral motion by dry friction.
- Friction between two surfaces causes kinetic energy from moving surfaces to be converted into thermal energy (that is, it converts work to heat).
- As demonstrated by the use of friction produced by rubbing pieces of wood together to start a fire, this property can have dramatic effects.
- Every time there is motion with friction, such as when a viscous fluid is stirred, kinetic energy is transformed into thermal energy.
- Wear is a significant side effect of many types of friction that can result in deteriorated performance or component damage.
- The discipline of tribology includes friction.
The formula of the friction force F = μN
where,
F = friction force
μ = coefficient of friction
N = normal force
