An example of not useful friction is the friction between the tires of a car and the road surface when trying to accelerate. This friction wastes energy in the form of heat and wears down both the tires and the road, without serving a beneficial purpose in this context.
Friction can be beneficial in situations where you want to slow down or control movement, such as in braking systems for cars. It can also be useful when trying to grip surfaces, like shoes on a slippery floor.
Friction is useful in helping cars stop when brakes are applied, as the friction between the brake pads and the wheels slows down the vehicle. Friction is also beneficial in walking, as friction between the soles of shoes and the ground prevents slipping and provides traction.
Friction can be beneficial in sports to improve grip and control, in transportation to help vehicles stop, and in construction to hold materials together. Additionally, friction is essential for walking and running as it allows us to push off the ground and move forward.

If there was no friction, nothing would come to a stop. Everything you touch, and every move you make, would continue and build momentum (speed).

Ways that friction are beneficial: Standing - Friction allows you to stay in position instead of moving around even when you do not want to Braking of cars - Similarly, friction makes it possible to make a car stop Ways that friction is nuisance: Wear and tear - Friction produces heat, which would flatten shoe soles, smoothing the gears or other mechanics in machineries

Friction is not required in sports like swimming and diving because it is beneficial for athletes to move through water with minimum resistance. Additionally, in sports like gymnastics and figure skating, reduced friction allows for smoother and more controlled movements during routines.
Increasing friction can be beneficial in applications such as car brakes, where higher friction helps to stop the vehicle more effectively. It can also be useful in sports like rock climbing or hiking, providing better grip and stability. Additionally, increased friction can aid in machining processes by improving control and accuracy.
In some cases, reducing friction can be beneficial, such as in machinery to increase efficiency and in sports to improve performance. However, friction also plays a crucial role in providing traction, preventing sliding, and enabling control in various situations. Therefore, balancing the need for friction reduction with maintaining safety and stability is important.
Friction is beneficial in brakes as it helps convert kinetic energy into heat, slowing down the vehicle efficiently. In tires, friction provides grip between the tire and the road surface, allowing for better traction and control of the vehicle. Both applications rely on the controlled use of friction to improve safety and performance.
Low friction can be useful for reducing wear and tear on machines and improving efficiency in tasks like sliding or rolling. High friction, on the other hand, can be beneficial for providing traction in tires or shoes to prevent slipping and ensure safety in various applications.
