Question

how can we change the frictional force between two objects​

Answer 1

Answer:

we can add lubricant to change the friction or if we change the angle between friction objects then also the friction will change.

I hope it clears to u

Answer 2

the answer to ur question is ⤵

➡

1. There are several ways to change the frictional force between two objects. The first one is to modify the surfaces of each object that will come in contact with each other. The smoother they get, the less friction there will be. But if the surfaces become rougher, more friction will be generated.
2. by polishing the surface with thr helps of lubricant
3. by making grooves.

hope it helps:)
