|x-1|+|x-2|+… +|What is the minimum value of x-2005______ ．

Since there are 2005 terms in the absolute value of the original formula, the middle term is | x-1003 |, so just take x = 1003, and the sum of them can get the minimum value. The original formula can be expanded as: | X-1 | + | X-2 | + | x-3 | + +|x-2005|=|1003-1|+|1003-2|+… +|1003-1003|+|1003-1002|+… +|1003-20...

What is static friction? What is dynamic friction? Give a few examples
Please give a few examples

1. Static friction when an object moves along the tangent direction of the contact surface or has a tendency of relative motion on the surface of another object, there will be a force between the contact surfaces of two objects that hinders their relative motion or the tendency of relative motion. This force is called friction
