Yes, friction exists whenever two objects touch. Friction is caused by two effects: direct contact of mechanical surface irregularities and the electromagnetic force. It has nothing at all to do with the gravitational force, the strong force, or the weak force.
No, sliding without friction is not possible. Friction is necessary for objects to slide against each other. Without friction, there would be nothing to oppose the relative motion of the surfaces in contact, causing them to stick together or slide uncontrollably.
Gravity exists regardless of weight, as it is a force of attraction between objects with mass. Weight, on the other hand, is the force with which an object is pulled by gravity, and it depends on the mass of the object and the strength of the gravitational field it is in. So, gravity would still exist even if weight did not.
In theory, yes, it is possible to pick up something without friction if the object is in a zero-gravity environment or if the force applied is greater than the force of friction. However, in everyday situations on Earth, it is difficult to pick up something without some level of friction present.
No, friction is not required for standing straight. Gravity and the interaction between your body and the ground provide the necessary support to maintain an upright position without the need for friction.
If friction did not exist, the ball would continue rolling indefinitely without slowing down or stopping. Friction is the force that opposes motion on surfaces, so without it, the ball would not experience any resistance to slow it down.
No, sliding without friction is not possible. Friction is necessary for objects to slide against each other. Without friction, there would be nothing to oppose the relative motion of the surfaces in contact, causing them to stick together or slide uncontrollably.
Yes, a sky would still exist even without gravity. Gravity is what holds our atmosphere close to Earth, but even without it, the atmosphere would still exist and interact with light to create the appearance of a sky.

No, Scientists have tried to create surfaces without friction but it has been deemed an impossible feat.
Yes. Without sliding friction or rolling friction, we would not be able to walk. It is the relationship between gravity, friction, and mass.
no , can't because it helps us in moving
Of course,energy forms like Light,sound do not have any connection with gravity.
It can, and it does. There's no connection between the two.
Without gravity, and friction the race car would be flying everywhere and would slide off of the track.
