Linear Momentum and Collisions
... In Chapter 8, we studied situations that are difficult to analyze with Newton’s laws. We were able to solve problems involving these situations by identifying a system and applying a conservation principle, conservation of energy. Let us consider another situation and see if we can solve it with the ...

Conservation of Linear Momentum
... Notes on determining the mass entering a system. The mass entering a system boundary (through an area) during a period of time may be determined or specified in many ways. 1. We can simple state that a certain amount of mass enters the system during a specified time period, i.e., m mass . in time ...

Calculation of an Atomically Modulated Friction Force in Atomic-Force Microscopy.
... 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 ...

Circular Motion
... Problem: For a car traveling at speed v around a curve of radius r, what is the banking angle for which no friction is required? What is the angle for a 50km/hr (14m/s) off ramp with radius 50m? To the free-body diagram! Note that we’ve picked an unusual coordinate system. Not down the inclined pl ...
