No, friction does not play a direct role in enabling humans to talk. Speech production is primarily a result of air passing through the vocal cords, which then resonate and produce sound waves that form words and sentences.
Rolling friction occurs when moving parts have ball bearings. This type of friction is lower than sliding friction, as the ball bearings allow the parts to roll smoothly over each other with less resistance.
When parts have ball bearings, the friction that occurs is rolling friction. This type of friction is lower compared to sliding friction because the ball bearings allow the parts to roll past each other with less resistance, reducing wear and improving efficiency in mechanical systems.
In machine components, such as bearings or gears, excessive friction can lead to wear and reduce efficiency. In sports, like ice skating or skiing, minimizing friction is desired to allow for smooth and fast movement.
The surface type affects the friction force by altering the roughness and texture of the surfaces in contact. Smoother surfaces generally have lower friction as they allow for easier sliding motion, while rougher surfaces create more resistance to motion, leading to higher friction forces. Additionally, the surface materials can also affect friction due to differences in their coefficients of friction.
Surfaces with very little friction include ice, polished metal surfaces, and Teflon-coated surfaces. These surfaces reduce friction because they have smooth textures or surface coatings that allow objects to slide over them with minimal resistance.
yes
Yes. Humans can talk.
Of course. Both of them can really talk. Humans and parrots can talk.
since humans talk when they breathe out and dogs do it when they breathe in this is the main reason why humans talk and they bark
That would be static electricity, caused by friction.
There are many reasons why friction is an advantage to human motion. Friction helps humans to stop when they need to stop.
wont allow
It keeps the roller down and creates friction to allow the roller to move.
No, cats cannot talk like humans at all.
humans talk, phones answer.
yes, i have pet ones, and they do talk to me
Of course humans can talk.
