Friction has advantage and disadvantage,

In that case friction causes wear and tear.

there are two activity to prove friction causes wear and tear.

1)some years back in a flight the nose landing gear failed.

it turned sidewards,

so when landing due to friction it caused fire and also the metal parts in the wheel was disappeared and also the the rubber tube was gone.

so, this activity proves us friction causes wear and tear

2)when the car is travelling 100kmph and when the driver put a sudden brake the car stops after a few seconds but if we see the tires it will not be as same as before the driver puts a brake it smooth and it will not have the threads in the tire. The threads in the car are damaged

so, this activity also proves that friction causes wear and tear.

Is there more friction on a rough surface show a picture?

Yes, there is more friction on a rough surface compared to a smooth surface. Rough surfaces have more irregularities that create greater interlocking between the surfaces in contact, leading to higher friction forces. Unfortunately, I'm unable to show pictures.


How did Leonardo discover friction?

Leonardo da Vinci did not discover friction, as it was already known in his time. However, he did study and make observations on the effects of friction in his work as an artist, engineer, and scientist. Leonardo's sketches and writings show his understanding of how friction influenced the movement of objects and the functioning of machines.


How can you show that momentum is not conserved between the balls when friction is strong?

If momentum is not conserved between the balls when friction is strong, you can show it by performing an experiment where two balls collide on a rough surface. Measure the momentum before and after the collision and observe if the total momentum changes. If the momentum changes, it indicates that momentum is not conserved due to the influence of strong friction during the collision.


How do you demonstrate an experiment to show that friction is a contact force?

To demonstrate that friction is a contact force, you can place a wooden block on a flat surface and try to slide it. Then, place a heavier block on the wooden block and attempt to slide it again. The increased friction between the surfaces in contact will make it harder to slide the blocks, showcasing the role of contact force in friction.


Give some examples to show that friction is increased deliberately?

One example is using sandpaper to increase friction between objects. Another example is applying anti-slip mats or tapes to surfaces to prevent sliding. Additionally, car tires are designed with treads to increase friction with the road for better traction.
