more friction increases speed
|
|
|
less friction decreases speed
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -How does friction affect motion? Friction always opposes the motion and reduces the speed at which the object moves on the surface. It will turn some of the kinetic energy of an object into heat energy, thereby reducing the speed.
Detailed explanation-2: -Therefore, the hydrolysis reaction is the main factor affecting the coefficient of friction. As the speed increases, the hydrolysis reaction decreases, which also explains the decrease in the coefficient of friction.
