Yes, there are: (1) lubricants, (2) ball bearings.
the invention the could change the world would be the teleporter
in.vent.ion=invention or misspelled word:e.vent.shon
Friction is decreased by means of lubrication.
friction can cause: 1) Physical wear and tear of moving parts. 2) degradation of materials by continuous friction. 3) wastage of 70% of energy in car engines. However, friction is useful in: 1) walking 2) car brakes, friction between brake pads and Tyre causes car to slow down. 3) techniques like friction welding.
there could be friction inside the motor. there is friction on the wheels of the scooter and the ground. there is air friction when you move on a scooter.
I am not quite sure of it, but I think it could be invent? INVENTion....INVENTor....you get it? LOL
Friction could be dangerous when it causes excessive heat generation, leading to burns or fires. Additionally, friction could cause wear and damage to moving parts, compromising the safety or functionality of machinery or equipment.
without friction you could be able to stay in one position
Friction is what holds, stops things from moving. if there was no friction then things would be on the move 24/7.
I found the invention really good because I could talk to my other relatives in the world.
This would be sliding friction and it could happen when:run on the floor
Modern inventions could be the invention of the wheel compared to the invention of bronze; or it could be digital, wireless communication.
