... the axis has to point towards the center (+ towards center). Decompose the forces that are not along the coordinates 3. Write down Newton’s 2nd laws for each direction and each object. For the one going around a circle the acceleration is ac=v2/R. 4. If more than one object determine their relation ...

... on B. In that case, C is given by the elastic constants of A at the interface (7], hence cannot be changed independently. Since c is rather large in many materials, zero friction should be observed for moderate applied loads in the absence of wear and plastic deformations. For a multiatom «tip» whic ...

... When two surfaces are pressed together, the high points on each side come into contact and form molecular bonds. The amount of contact depends on the normal force n. When the two surfaces are sliding against each other, the bonds don’t form fully, but they do tend to slow the motion. © 2013 Pe ...
