35. (I) When two objects which are touching try to move past each other,they rub against each other. (II) This produces a force called friction which tries to stop the movement. (III) If they are smooth and slippery.especially if lubricated with oil or grease, then friction is less. (IV) Therefore , we can conclude that friction is the enemy of machines because it opposes movement, causes wear and tear, and changes useful energy into waste heat. (V) But if the surfaces of the objects are rough , like sandpaper, then friction is greater. A) 1 B) II C) III D) IV E) V
