In order to make a model of an underwater bullet, I first need some data. This video is actually very nice for video analysis since it follows some of my guidelines: Stationary camera. View ...

Displacement close displacementA distance measured in a specified direction. is the distance moved in a straight line, in a given direction, from the starting point. Displacement = 24 m east. Velocity ...

If the angular velocity of a link in a mechanism is zero, does this imply that the angular acceleration of that link is also zero? The short answer to that question is NO. If ω(t) represents the ...

Figure 3: The damping force as a function of velocity for oscillatory (a.c.) motion compared with steady (d.c.) motion. Figure 4: The processes involved in oscillatory (a.c.) motion. Suppose the ...
