Gravity pushing you down on the earth and friction from the ground are the two types of friction you have to overcome when walking.
Static friction must be overcome to start movement of a stationary object. This is the friction that exists between two surfaces that are not moving relative to each other. Once the static friction is overcome, the object can start moving.
False. The force required to overcome static friction is generally higher than the force needed to overcome kinetic friction. Static friction is the resistance to the initial movement of two objects at rest, while kinetic friction is the resistance to the motion of objects sliding against each other.
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.
The kinetic friction coefficient is a measure of the resistance between two surfaces in motion. A higher coefficient means more force is needed to overcome the friction and keep the surfaces moving.
No, walking is not an example of static friction. Static friction occurs when an object at rest is being prevented from moving by a force applied parallel to the surface it's on. Walking involves kinetic friction, which occurs when two surfaces are in contact and one is moving relative to the other.

No, the force needed to overcome static friction is generally greater than the force needed to overcome kinetic friction. Static friction occurs when two surfaces are at rest relative to each other, requiring more force to overcome the initial "sticking" friction. Once the surfaces are in motion, kinetic friction occurs and typically requires less force to maintain motion.
Static friction is typically the most difficult type of friction to overcome because it requires the most force to initiate motion between two surfaces. Once an object is in motion, kinetic friction is usually easier to overcome because the surfaces are already moving relative to each other.
You would have to overcome sliding friction to make a book move across a desk. Sliding friction is the force that resists the motion of two surfaces sliding against each other.
Static friction is generally harder to overcome than kinetic friction because it requires more force to initiate motion. Static friction occurs when two surfaces are at rest relative to each other, while kinetic friction occurs when the surfaces are moving against each other.
This statement is not always true. The force required to overcome starting friction can sometimes be larger than the force required to overcome sliding friction due to factors like surface roughness, adhesion, and lubrication. It depends on the specific properties of the materials and the conditions under which they are in contact.
Static friction typically requires more force to overcome compared to kinetic friction because static friction opposes the initiation of motion between two surfaces, while kinetic friction opposes the relative motion of surfaces that are already moving against each other.
