What is the effect of decreasing the block in contact with the table on kinetic friction?
less friction
What way does the friction act if you're pulling a nail out of the block of wood?
Friction acts towards the nail in the block when you are pulling it out. In other words, it will try to keep the nail in the block and not let it be pulled out by the hammer.
Is the coefficient of friction the same as when the block was standing on its larger (or smaller) end?
The coefficient of friction is the same in this case.
How does friction affect newton's third law?
Friction is encompassed by Newton's laws, as opposed to operating out side of it. If a block slides down a wedge, there is friction acting against the block up the slope. From the wedge's perspective, the block produces a frictional force against it, trying to drag it downwards along the slope.
A block of wood is at rest on a wooden ramp. When wheels are attached to the block of wood it moves down the ramp. Explain each situation in terms of friction.?
first it will have static friction because the object isn't moving.once it rolls it will have rolling friction.

A block accelerates at 3.2 down a plane inclined at an angle 30 degrees. Acceleration of gravity is 9.8. Whats the coefficient of static friction between the block and the inclined plane?
Static friction does not apply when the block is already moving. Without friction, the force on the block parallel to the surface of the incline is Fg*sin(angle), so the acceleration without friction is 9.8* sin(30) = 9.8 * (1/2) = 4.9 Since it is accelerating at 3.2, friction is slowing down the block by (4.9-3.2 = 1.7). The coefficient of kinetic friction is (1.7/4.9) = 0.346939

Does the coefficient of kinetic friction depend on the weight of the block?
No, It does not depends on weight of block because this weight of block is being balanced by normal force. So by increasing weight of block, there is no effect on coefficient of friction.
What terms of friction would I use to describe a block of wood when it is at rest on a wooden ramp then when I add wheels to the block of wood to make it go down the ramp?
at rest it is static friction while on wheels it is rolling friction

The coefficient of friction is the same in this case.
What is kinetic friction and static friction?
Friction is the resistance to movement of an object pressing/resting/moving on a surface. It's not intuitively obvious but the standing still friction and moving friction are different. Assume you have a block of wood resting on a tabletop. The amount of force required to make the block begin to move (static friction) is greater than the force required to keep it moving (kinetic friction) after it has begun to move.

Friction block uses?
for the use of life. , it will contribute to the country.
What will stop a block of wood across the floor?
Friction will stop it.
Why is a block of wood get warm when it is rubbed with sandpaper?
because of friction
