A world without friction would be chaotic, as objects and people would have no way to stay in place or move efficiently. Tires and shoe soles would not be able to grip the ground, leading to accidents and difficulties in transportation. Knots would come undone easily, and nails would not stay in place, making construction and everyday tasks extremely challenging.
If there was no friction, your shoelaces would not stay tied, as friction between the laces and knots is what keeps them in place. Without friction, the laces would easily slip and come undone.
Knots do not slip when we pull them together because of friction between the strands. The friction creates resistance that prevents the knot from unravelling or slipping. Additionally, the structure of the knot itself, when tied correctly, helps to lock it in place.
A Boeing 747 typically requires a ground speed of around 180-200 knots (207-230 mph) for liftoff. This speed varies depending on factors such as aircraft weight, weather conditions, and runway length.
No, an aircraft carrier cannot go 100 knots. The top speed of an aircraft carrier is typically around 30-35 knots, which is fast for a ship of its size but much slower than 100 knots.
Technically, but unlikely. For instance, a slow airplane is capable of staying in the air at about 30 knots/34 mph. 34 mph is a pretty strong wind, but in hurricanes, winds can be as fast as 150 mph. If a plane is flying directly into the wind at 30 knots, and the wind is blowing at 30 knots, the plane will not be moving relative to the ground. (Ground speed zero). The planes airspeed will still be 30 knots. NASA has a plane that goes very slow (slower than a bicycle). In a stiff wind, it will go backwards relative to the ground. Most pilots wouldn't fly in a wind that was blowing at a speed capable of holding them in one place. Not because of any danger in the air, because there wouldn't be, but because landing (on the runway) would be extremely difficult to impossible.
That sounds kind of like a world without friction.

No, knots rely on friction to hold them in place, so without friction, knots wouldn't be effective in securing items.
Reef knots are used for first aid because they lay flat and are easily undone.
For grip between the player and ground there are knots under the soles of the football boot.
Wood without knots is called Number 1 B-grade wood. B-grade is a better wood with little to no blemishes or knots.
Knots do not slip when we pull them together because of friction between the strands. The friction creates resistance that prevents the knot from unravelling or slipping. Additionally, the structure of the knot itself, when tied correctly, helps to lock it in place.
It depends on the airplane. i.e. a cessna needs around 70 knots while a Boeing 747 needs around 250 knots.

Deep tissue massage focuses on releasing chronic tension and knots in muscles and connective tissue. It involves stretching, friction, and deep pressure.
