rubbing your hands together produce heat that is friction.
A car is an example of a machine where friction can be both an advantage and a disadvantage. Friction between the tires and the road allows the car to accelerate, brake, and turn smoothly, providing traction. However, friction also causes wear and tear on the tires and causes the engine to work harder, leading to decreased fuel efficiency.
No, the ideal is without friction.
There are many reasons why friction is an advantage to human motion. Friction helps humans to stop when they need to stop.

An example of a non-frictional force is gravitational force. For example, when an object is in free fall, there is no friction acting on it.
Mechanical advantage is determined by physical measurement of the input and output forces and takes into account energy loss due to deflection, friction, and wear. The ideal mechanical advantage, meanwhile, is the mechanical advantage of a device with the assumption that its components do not flex, there is no friction, and there is no wear.
Friction is not typically considered when calculating the ideal mechanical advantage. The ideal mechanical advantage assumes no energy losses due to friction, but in real-world applications, friction can reduce the efficiency of a machine.
An example of fluid friction is the air resistance felt by an airplane.
A example of friction is rubbing your hands together the heat you feel is friction. Oh dont be a shat head.
Rolling Friction, Static Friction, Sliding Friction, & fluid Friction
A piece of sand paper on a piece of wood is an prime example of rubbing friction.
