Why do moving objects on earth always experience friction while objects in outer space usually do not?
Lydiathegreat
Friction is caused by the movement against anything, including the atmosphere, which grows thinner and thinner as you leave the planet. (It is also why planes fly so high in altitude - less friction means greater miles per gallon of jet fuel.)
As an experiment, part your fingers such that there is air (or space) between them all; then run your wrist either side to side or forward and backward very rapidly so that you will feel the friction of the air against your fingers.
This cannot happen in a vacuum of space, not that you could even attempt it.

What direction does friction act in to an object's direction of motion?
Friction will always act in the direction opposite of the relativistic motion of two objects. If object A is moving to the right on object B, then object A will experience the friction to the left. However, object B will be moving to the left on object A and will therefore experience the friction acting towards the right.
Which direction does friction always work?
Friction's direction is always against the direction work is being applied to.
When are the forces acting on the object?
Depending on the scenario the forces act on the object when there is actually a force being acted on it? Gravity is always acting on objects (unless space) Friction acts on object as long as object is moving on a surface with friction There are a bunch of other forces but these are just examples
What is the effect of friction on motion?
Friction reduces velocity because it is the force responsible for the resistance to motion of objects on surfaces or in fluids. For example, bowling alleys have very low friction whereas sandpaper has extremely high friction.
Does heat always flow from cooler objects to warmer?
Heat always flows from warmer objects to cooler objects, unless you have a device (like a heat pump) to prevent this. The natural tendency is for two or more objects at different temperatures to eventually all have the same temperature and this is accomplished by heat flowing from the warmer objects to the cooler objects.
How does friction always effect the motion of objects?
Friction inhibits the motion of objects.
Does friction cause the speed of moving objects to increase?
No, the force of friction always acts in the direction opposite to that of the motions.
Does friction help objects speed up or slow down?
Friction always works against the velocity and so it always works to slow down an object.
What direction does friction act in to an object's direction of motion?
Friction will always act in the direction opposite of the relativistic motion of two objects. If object A is moving to the right on object B, then object A will experience the friction to the left. However, object B will be moving to the left on object A and will therefore experience the friction acting towards the right.
How does the direction of the force of kinetic friction is related to the direction of of an objects motion?
Friction always acts opposite to the direction of motion.
How the direction of the force of kinetic friction is related to the direction of an of an objects motion?
Friction always acts opposite to the direction of motion.
Why do objects remained at rest?
As you can observe, they will not ALWAYS be at rest. Objects have a tendency to remain at rest, because:* Inertia means that if no force acts on an object, it will remain at rest if it was at rest; or, if it was moving, it will continue moving at the same velocity. * Friction forces will usually slow objects down.
What has 0 friction?
There is no such thing as zero friction, when an object is moving it will always loose heat/energy to the objects around it. Even if it is a solid object or air, E is always being transfered. If there was someting that had no friction it would continuously be moving.
What is static friction in sliding friction?

Friction always acts in a direction?
Friction always acts in the direction opposite to the the motion of the object.For example, if a bowling ball rolls to the right, friction would act to the left.Without friction, if you threw a ball, it would keep going forever. Friction slows objects down.
Friction acts in a direction of what to the direction of an objects motion?
Friction provides a retarding force. It always acts in the exact opposite direction of the motion of the object.
Is it true that rolling friction always reduces the net force acting aginstan objects's motion to zero?
Friction can be reduced, but in most cases there is no practical way to reduce friction to zero.
