Rotational motion and torque notes
... object rotates through angle in time t. The angular speed or velocity is given by (remember, in translational motion v = d/t) = /t Angular speed (velocity) can be converted to the analogous translational speed (velocity) using the radius. = v/r where v is the tangential velocity Angular veloc ...

Chapter 7 Impulse and Momentum continued
... A 9-kg object is at rest. Suddenly, it explodes and breaks into two pieces. The mass of one piece is 6 kg and the other is a 3-kg piece. Which one of the following statements concerning these two pieces is correct? a) The speed of the 6-kg piece will be one eighth that of the 3-kg piece. b) The spee ...

Newton`s Third Law. Multi-particle systems
... We have seen that the magnetic force between two particles need not obey Newton’s third law. What becomes of momentum conservation? The answer is that the momentum ledger must include contributions from the electric and magnetic fields. Do you recall that these fields carry energy and momentum? Taki ...
