Friction wastes more work on longer planes because the distance over which friction acts is longer, resulting in more energy lost as heat. This leads to a greater decrease in the mechanical energy of the object moving along the plane.
Its longer cuz the longer the flatter the incline plane, and on flatter planes, the object presses more than on the shorter ( steeper ones)
Friction wastes more work on longer distances due to the increased surface contact and the higher energy required to overcome it. Shorter distances have less surface contact and require less energy input to overcome friction.
Friction wastes energy by converting kinetic energy into heat as two surfaces rub against each other. This results in a loss of energy that could have otherwise been used in the intended motion or task. Therefore, friction is a source of inefficiency in systems where energy conservation is desired.
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 in a pulley can reduce the efficiency of the system by causing energy loss in the form of heat. It can also cause wear and tear on the pulley and the rope or belt running over it, leading to maintenance issues and reduced lifespan of the components. Overall, friction in a pulley can hinder smooth operation and reduce the overall performance of the system.

Friction has two unpleasant effects: 1) it increases wear and tear, 2) it wastes energy.

In several cases, friction can be a real nuisance, mainly because it wastes energy. Thus, in many engines, where there are moving parts, you'll want to decrease friction to waste less energy.

Friction always wastes energy and heat is produced
Friction has two unpleasant effects: 1) it increases wear and tear, 2) it wastes energy.
Machines with moving parts will have some amount of friction that makes them less efficient, wears them out, and can make them overheat. In a pump, a piston moves up and down inside a cylinder. If it rubs against the wall of the cylinder, that wastes energy. It should move with minimal friction.
