Ways to Reduce Friction
Try pushing a heavy box across a rough concrete floor. It feels hard to move, right? That’s because of the friction between the two surfaces in contact.
Now, imagine placing the same box on a smooth surface. It slides more easily.
Rough surfaces have tiny bumps that lock together. When we polish or smooth a surface, those bumps become smaller, which reduces friction.
That’s why skating rinks and slides are smooth—to help things glide easily.
Another way to reduce friction is to use lubricants like oil or grease. That’s why bike chains and door hinges are oiled.
Lubricants fill the tiny gaps between surfaces, allowing them to move with less effort. Machines often use them to keep parts moving smoothly.
Rolling instead of sliding also reduces friction as wheels don’t rub against the surface. So, moving a suitcase or a cart with wheels feels easier.
Ball bearings are another way to reduce friction. Tiny metal balls are placed between moving parts. They roll instead of sliding, helping the parts move smoothly.
Reducing friction makes movement easier and also saves energy.
