WebMar 28, 2024 · Answer. Question 10. Lubrication reduces friction because. (а) the relative motion is between the liquid and solid. (b) laws of limiting friction are not applicable. (c) … WebThe friction now acting between the surfaces of contact is dynamic friction. The dynamic friction is always less than the limiting static friction. Dynamic friction is of two types: Sliding Friction; Rolling Friction; Sliding Friction: If one body begins to slides over the other, then the friction between the surfaces is called sliding friction.
