Question

friction is the force that one surface exerts on another when they rub together. friction works in the direction opposite to the motion, causing the object to slow down. what is one way you could reduce the friction between two surfaces? a carpet the surfaces. b put oil on the surfaces. c put sand on the surfaces. d allow one of the surfaces to rust.

Explanation:

Friction can be reduced by using lubricants. Oil is a lubricant that decreases the roughness between two surfaces, reducing the frictional force. Sand increases friction, carpeting the surfaces may not necessarily reduce friction in all cases, and allowing one of the surfaces to rust will likely increase irregularities and thus friction.

Answer:

B. Put oil on the surfaces.
