Sliding friction is always greater 보다 rolling friction. Imagine a auto with square wheels. Rolling friction is applied widely in our daily lives.
Examples in our everyday lives: sphere bearings use balls to different two bearing races. Hence sliding friction is converted right into rolling friction. The gyeongju won’t slide end each other now yet transfer the fill to the balls v rolling friction.
You are watching: What are two ways to reduce friction
6. Minimize pressure or load on the object
Friction is directly proportional come the typical force used to it. Due to the fact that we space on earth, the load of the body is the normal pressure on the object generally. In space, there will certainly be really less or no friction. So, choose materials wisely to reduce friction.
7. Use fluid friction instead of the dried friction
Fluids offer much less friction contrasted to heavy surfaces.

That is why aircraft deserve to travel in ~ high speeds compared to cars. Also, as soon as we are applying lubricants or oil ~ above surfaces, we are basically converting dry friction into fluid friction.
