Sex has a friction when people go up and down and up and down and pole dancing does.
The force created when an object rolls over a surface is called rolling friction. This force opposes the motion of the object and is responsible for slowing down the rolling motion. Rolling friction is generally lower than static or kinetic friction for sliding objects.
Correct me if I am wrong, but I think the temperature determines which objects stop on which surfaces!!
It had better be! Otherwise, nothing could ever start sliding ... as soon as yourpull on the string becomes strong enough for the object to break free of thestatic friction and begin to slide, the force of kinetic friction would take over,and it would suddenly be even stronger!
Kinetic friction is commonly thought of as the friction between two objects while those two objects slide against each other. To determine the coefficient of kinetic friction (for an object under the influence of gravity on some surface), one needs to determine the angle at which the sliding object moves at a constant speed down the other object (think of a flat piece of rubber sliding down a flat plank of wood). This is different from static friction where the sliding object has some applied force to move along a surface, but that object is stationary because of the friction applied by the surface. To determine the coefficient of static friction, one needs to determine the angle at which the sliding object begins to move down the surface.
An example of sliding kinetic friction is pushing a box across the floor. As the box moves, there is friction between the box and the floor opposing its motion. This friction force must be overcome by applying a force in the direction of motion.
i think it it rolling friction
No. Friction is a measurable force observed between two objects sliding/rolling along each others surface. Shear is the act of cutting. The process of friction could shear something. Think glaciers.

Yes, friction can be transferred during a collision when two objects bounce apart. Friction between the surfaces of the objects can play a role in determining the direction and speed of the objects after the collision. The amount of friction transferred would depend on factors such as the materials of the objects and the forces involved in the collision.
It provides static friction, so the object cannot move until the static friction is overcome. For example, if the object at rest had 5N static friction, it would take 5.1N to make the object start moving.
Well if you did not have friction you would fall over when you walked. Just think of what it is like trying to walk in ice (which has very low friction).
Friction is the force that resists motion between two surfaces in contact. In the vacuum of space, there are no surfaces or molecules to create this friction. Objects in space can move freely without friction because there is very little resistance to their motion.
If I understand the question correctly: It is actually ill-posed. The frictions you are refering to are dynamic (sliding) and static (starting). I think you will find that static friction is always harder to over come than dynamic friction, not vice-versa.
