Why does not having friction make it unsafe to use small rugs on the floor?

If there is no friction between the rugs and the floor, they become large skating objects that can easily dump you on your rear end, possible breaking bones.

What can cause loss of energy?
According to the laws of thermodynamics, energy can never be "lost" or "made". Energy, in a closed system, is always constant. Energy can however be "lost" to the environment, for instance by friction. If you drag a box over the floor, some of the energy you are putting into moving the box is being "lost" to the environment by friction between the box and the ground (and a very small amount to air friction). You could therefor say that friction is a cause for "loss" of energy.
Where does the friction need to be small on a hinge?
The friction on a hinge needs to be small at the pivot point where the hinge rotates. This allows smooth movement and prevents the hinge from sticking or getting stuck. However, in other parts of the hinge, such as the pins or brackets, a small amount of friction may be desirable to provide stability and prevent excessive movement.
What kinds of substance reduce friction?
Friction is the act of one surface rubbing against another. To reduce friction, use something that offers a small amount of friction. Smoother substances reduce friction. A way to reduce friction is to use something which offers a small amount of friction. For example, you could use something like plastic or glass. Water, most liquids and different types of oil reduce friction. Powder, oil and grease are used in between surfaces to also reduce friction.
What is the difference between static friction and sliding friction?
Sliding friction is always less than the static friction by small amount.
What does smooth surface mean in friction?
It then presume the friction is very small and presume no friction. In fluid and piping, it mean any pressure drop term is due to fluid motion and dispersion alone.
When paper is dragged on the floor why does it slow down?
the paper slows down due to gravity, and friction, there are small hills and valleys that are not seen.
What if your 2 ton floor jack leaks leaving a small puddle of oil where you used it?
If the jack drifts down when weight is on it, the seals are failing. The jack would be unsafe at that point.
What is significant friction?
Friction that effects the object in motion. insignificant friction is friction that is so small it is negligible.
Where is small friction made on a bike?
In the bearings

Why is it unsafe to collect to much hydrogen effort testing it with a lit splint?
This is unsafe because the small scale experiments done by classes are only producing a small explosion (the POP noise), whereas an increased amount of concentrated hydrogen can cause a larger scale explosion, which might be very unsafe. Happy learning! :)
