What are the different ways to reduce friction? - Teachoo

WebIn a frictionless surface, if a body or an object is in motion, it is best to apply an external force opposing the direction of motion of the body or the object in motion to decrease its speed of motion on the frictionless surface. The equal and opposite forces would cancel each other, finally leading the movement of the body to stop. Web18 mrt. 2013 · Rolling friction is less than sliding friction, thereby decreasing the amount of friction in the machine. Other ways to decrease friction By polishing.
