Question

if normal force is double, what happens to friction? explain​

Answer 1

Explanation:

The coefficient of friction is a property of the two surfaces in contact. If we double the normal force, we double the amount of friction, but the coefficient of friction is the same, since the nature of the two surfaces in contact has not changed.

Answer 2

Explanation:

If we double the normal force, we double the amount of friction, but the coefficient of friction is the same, since the nature of the two surfaces in contact has not changed.
