Is it possible to zero friction?
No, we cannot have zero friction surfaces. We can reduce the friction but we can never reduce it to zero because every surface will still have minor in them. A frictionless surface is not possible is not possible because the surface cannot have a zero friction surface.
Is there anything that has no friction?
A: Motion is indeed possible without friction! These also don’t require friction. Newton’s first law states that objects with no external forces on them will continue to move in the same direction at the same speed.
What happens when friction is zero?
There is no net force, so there’s no motion. Friction is actively responding to the applied force and thus exists. Until the static friction is overcome, there will be no motion, and if no additional force is applied, these two forces could continue opposing one another for as long as you like.
Is perpetual motion possible without friction?
To keep a machine moving, the energy applied should stay with the machine without any losses. Because of this fact alone, it is impossible to build perpetual motion machines. This friction will ultimately cause the machine to lose its energy to heat.
Can friction exist without gravity?
Yes friction can exist without gravity. Because only thing u need to create friction is force no matter where it is privided.
Why we can reduce friction to zero?
Friction can be reduced by polishing surfaces or using large amount of lubricants such as oil, water, or grease but we cannot reduce friction to zero. Friction exists at even atomic levels too. We cannot completely eliminate friction.
What if there was no friction for 1 minute?
Friction stops things from sliding apart. If there was no friction everything would slide to the lowest point. It would be impossible to climb up anything. With no friction the only possible movement would be falling to a lower point under gravity.
Does friction exist in a vacuum?
The results seemed to go against the laws of physics: The vacuum, by definition, is completely empty space and does not exert friction on objects within it. As a decaying atom moves through the vacuum, it really does experience some kind of force resembling friction.
What will happen if there is no gravity on Earth?
Humans and other objects will become weightless without gravity. If we have no gravity force, the atmosphere would disappear into space, the moon would collide with the earth, the earth would stop rotating, we would all feel weightless, the earth would collide with the sun, and as a consequence.
Which has least friction?
Rolling friction produces the least friction.
