design or provide with a form that presents very little resistance to a flow of air or water, increasing speed and ease of movement.
"engineers can reduce a vehicle's fuel consumption by reducing its size and weight and by streamlining its body"
2 By polishing the surface, as polishing makes the surface smooth and friction can be reduced. Using lubricants such as oil or grease can reduce the friction between the surfaces. When objects are rolled over the surface, the friction between the rolled object and surface can be reduced by using ball bearings.
Explanation:
STREAMLINING. When objects move, the air around them generates a type of friction called air resistance, or drag, that slows them down. Fast-moving objects such as cars, trains, and aeroplanes are all streamlined ? designed with curved and sloping surfaces to cut through the air and reduce drag.
