Friction is a force that must be overcome for no useful purpose. It takes energy to do this, and thus is wasteful.

Advantages of Dry Friction: Enables Motion Control: Friction provides the necessary grip for walking, driving, and holding objects without slipping. Braking and Stopping Power: Dry friction is essential in braking systems — it helps vehicles and machines stop effectively. Energy Conversion: Friction converts kinetic energy into heat, which can be useful in processes like matchstick ignition or clutches. Mechanical Functionality: It allows belts, pulleys, and other mechanical parts to function without slipping. ❌ Disadvantages of Dry Friction: Energy Loss: Friction generates heat, leading to energy loss and decreased mechanical efficiency. Wear and Tear: It causes gradual damage to moving parts, increasing maintenance costs and reducing lifespan. Noise and Vibration: Excessive friction can create unwanted noise and vibrations in machinery. Requires Lubrication: In many systems, it must be controlled or reduced using lubricants, which adds cost and complexity.

Disadvantages of friction include energy loss in the form of heat, wear and tear on surfaces, reduced efficiency in machines, and difficulty in moving objects.
These are a few of the great many advantages and disadvantages of having friction in sport: Friction allows a running person to stop, change direction, jump, catch a ball, and throw a ball. Friction between a ball and the air limits how far it can be thrown (although gravity has an even greater effect). Runners require energy to overcome the friction between their feet and the ground.
friction can cause the wearing away of surfaces
because we cant walk , hold articles , we cant write and the construction of house is impossible. but there are some disadvantages in friction.
Advantages of friction: It allows us to walk without slipping, helps stop moving objects, and provides grip for vehicles on roads. Disadvantages of friction: It causes wear and tear on surfaces, reduces efficiency in machines, and can generate heat leading to energy loss.
Friction generates heat, leading to energy loss in mechanical systems. It can also cause wear and tear on the surfaces in contact, reducing their longevity and efficiency.
Rolling friction can cause energy loss due to the deformation of surfaces in contact, leading to reduced efficiency. Additionally, rolling friction can cause wear and tear on the surfaces in contact, requiring maintenance and replacement.
1) In machines the mechanical parts which rub with each other wear out. 2) Due to friction between the sole of the shoe and the floor the sole wears out. 3) Tyres of vehicles wear out because of friction. 4) Energy is wasted in overcoming the force of friction.
