1- A streamlined body structure helps in decreasing friction as it helps to move through fluids easily-2-When two objects are pressed harder against each other- their irregularities lock tightly and increase the friction-3-Grease acts as a lubricant that reduces friction by forming a layer between two surfaces in contact- thus preventing them from directly rubbing against one another-4- A smooth surface has fewer irregularities and hence offers less friction-
