What Are The Advantages And Disadvantages Of Friction? ›

The advantage of friction is it is used in automobile brakes in order to stop the vehicle and it is important for us to walk on the earth. The disadvantage of friction is it causes more heat which results in a waste of energy.

We walk freely on a surface due to friction because friction between the sole of our shoes and the ground prevents us from slipping over the ground. Friction helps to support the ladder against a wall. Objects can be piled up without slipping. Breaks of vehicles work due to friction.

With friction of feet/ shoes on the surface, help to speed. Frictional forces help to move the object in the speed. For example, spikes are used by the athletes to run fast. Wastage of energy: Excess of friction means extra energy, thus energy is being wasted.

Heat is generated at this surface of contact due to the opposing force of friction. This causes wear and tear on the material of the moving body. Hence, more work is required to put on a moving body so that it can overcome the force of friction and move forward.

Below is a list of friction's negative impacts: A lot of heat is generated by friction in various mechanical parts, which wastes energy as heat. Restricts motion, requiring more energy to overcome it. Making noise while operating a machine wastes energy and is annoying.

Friction force opposes or resists the relative motion between the two surfaces of objects in contact. It always acts in the direction opposite to that of the applied force or in the direction opposite to which an object moves or tries to move. It is a contact force.

Force can change the speed of a moving object. Force can change the direction of the motion of the a moving object. Force can change the shape of an object. Force can change the size of an object.

Friction is also the reason for decreased speed of playing objects on ground as well, due to resistance by uneven ground. Sliding or movement of fallen person causes increased injury due to friction, as it causes heat and resistance to movement of body. Wear and tear of ball and other objects is also a common example.

Wear and tear of objects:- due to friction, there is wear and tear of objects. Lubrication is used to allow the parts to move easier, moreover, prevents wear and tear. Wastage of Energy:- Excess of friction means extra energy, thus energy is being wasted.

Running shoes: Friction would be an advantage because the shoes need to grip the pavement. Bicycle brakes: Friction would be an advantage because it would allow the bicycle to stop. Slippery slide: Friction would be a disadvantage because it would make it difficult to slide.

Friction helps and is hence desirable when drawing, walking, driving or picking up fallen objects. However, it is not desirable when it causes rubber pads to be rubbed off and causes wear and tear. Option C is the answer.

Advantage: In some cases, friction-generated heat is desirable. For instance, it's used in various industrial processes like welding, drilling, and machining, where controlled heat generation aids in shaping or joining materials.

Three situations in daily life where friction is an advantage: 1) Walking - Friction is required between the feet/footwear and the ground to prevents slips. 2) Mechanical Brakes - Mechanical brakes help in slowing down the motion of a machine whenever desired. For example, friction is required to bring a car to rest.

The most common harmful friction happening is the grazed knee or elbow when you trip and land on a hard rough surface. Another is rope burn which can be very scarring. If you're sliding down a rope to save your life, there's no way you can save your hand. Ouch!
