WebAug 2, 2024 · Friction. Friction is that force which opposes the motion of two objects upon each other. Friction generates only when two objects are in contact with each other. When an object tries to move on other objects than an opposing force develops and resist this movement known as Friction. The friction force is likely to terminate the movement if … WebMar 28, 2024 · Answer. Question 10. Lubrication reduces friction because. (а) the relative motion is between the liquid and solid.
