Gravitational force and the force of friction (the friction of the object and the air).
my dear gravity is forever greater than friction and strong atomic force is greater than gravity
Static Friction and Kinetic Friction. Static Friction is what friction that slows you down. While Kinetic friction is sliding friction.
Lubricants reduce friction by replacing sliding friction with fluid friction.
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!

Geologists collect data on friction along the side of faults so that they can predict how much pressure is applied on the faults so they can predict how strong the earthquake is.
Electromagnetic Force
It sandwiches the clutch friction plate to the flywheel. The flywheel is connected to the engine, the friction plate is connected to the gearbox. Strong springs inside the cover plate hold the friction plate firmly to the flywheel. When the clutch lever is operated, springs in the cover plate are compressed, thus releasing the pressure on the friction plate, disengaging the gearbox from the engine.

Friction is useful when I want to stand up (trying to stand on a frictionless surface is difficult, and dangerous), but more friction is a problem when I am ice skating. Friction with my car tires is useful when I am driving on a road (especially if I want to stay on the road around a curve, or want to speed up or slow down), but more friction on the moving parts of the engine is a problem.
i think it it rolling friction

Static friction
The large body will have a strong force of opposing friction, related to its large weight. The force of friction between two materials is equal to the normal (perpendicular) force between them, times a factor (the so-called coefficient of friction), which depends on the materials, but is typically less than one.
Titanium is light strong and will not burn-down because of the over heating that is caused because of friction.
