No force holds objects up.
Gravity causes objects to attract each other, which makes it look like objects fall to the earth.
Objects in orbit stay in orbit because their velocity tangential to the object they orbit is sufficient to cause their falling due to gravity to bend into a continuous free fall.
Traction is a combination of friction and the "normal" force of the weight due to gravity. If there was no gravity, you wouldn't have any traction. And obviously, if you are following James Bond's Aston Martin and he sprays oil on the road in front of you, then oil will reduce the friction and you won't have much traction. Which was why the villains always crashed.

Traction involves applying a pulling force on a fracture in order to restore normal alignment.

Electric Force is the force between charged objects.
The mass of the two objects and the distance between them control the force of gravity between them. The equation for the force of gravity between two objects is Fg=(GMm)/R2, so if two objects are very massive, the force will be greater, and if two objects are very close the force will be greater. The force of gravity is directly related to the mass of the objects and inversely related to the distance between them.the earth
Friction between the tire rubber and the road give traction.

Traction is a loose term describing the amount of friction an item has. Friction is a type of force.
In physics, traction is friction between two objects that are touching. When a car in on ice, the coefficient of friction between the tires and the ice is very low. This is when the car is said to have "no traction." In reality it has some traction, just a relatively small amount of traction when compared to it's momentum. Traction is friction. Oh, and the centrifugal force doesn't exist. It's a fool's way of explaining centripetal force. Ask more tech/physics/math questions at www.electricalninja.com in the "Ask a Ninja" section.

Traction involves applying a pulling force on a fracture in order to restore normal alignment.
Absolutely ALL objects does this. Large objects, much force. Small objects, little force. Black holes, Humoungus force.

The pulling force to hold a bone in correct alignment is called traction.
Electric Force is the force between charged objects.
Low tire pressure gives you better traction,especially in sand.Low tire pressure gives you better traction,especially in sand.
When an objects net force is zero, its acceleration is zero. No force , no acceleration.
