Friction is the force that opposes the motion. It is the force between two surfaces rubbing together. Actually there are three kinds of friction:
static friction - friction occurs at rest. It is also the strongest type of friction.
kinetic friction - friction that occurs when an object is in motion.
rolling friction - the weakest of all the three.
So that's the basic definition of friction and its kind.
add Commonly, the status of the friction alternates between static and sliding many times per second. Commonly called 'slip stick' friction. This is the cause of a squeaky door hinge, the crunch of snow, and even if some remarkable 'singing sands' in some deserts.
[Alongside a squeaky door hinge you'll often find a deposit of fine dark powder - this is iron dust - some of the iron actually torn off the hinge surface in moving between these two frictions. ]

What are two main types of friction?
The two main types of friction are kinetic and static.
What two sources of friction do you have to overcome when walking?
Gravity pushing you down on the earth and friction from the ground are the two types of friction you have to overcome when walking.
List the two types of friction and give an example of each?
give 2example of friction
What are two sources of friction?
Not sure if you mean 2 types of friction. Two types of friction can be just friction with the ground, and air friction such as drag on any vehicle, or any type of flying machine. Other objects can have air friction too, but not as much as something moving at a higher rate of speed.

What are the 4 types of friction?
Friction is the name of the force which opposes motion between two items which are in contact with one another. The four types of friction are sliding, rolling, static, and fluid.
