... with respect to A, v CA ? This was for the x-component of the velocity, so we can write that explicitly, Distances in the y- and z-directions are not affected, but time is affected. So the velocity components in the y- and z-directions are ...


Speed and Velocity

... is If an antique car travels 45 km in 3 h, then its average velocity is Things do not always move with a constant velocity. The velocity may change. The instantaneous velocity is the velocity "right now", the velocity at some particular ...

Newton's SECOND Law of Motion

www.ux1.eiu.edu/%7Ecfadd/3050/Ch04Nwtn2ndLaw/Terminal.html

Newton's SECOND Law of Motion Terminal Velocity Consider a parachutist who jumps from a perfectly good airplane. What forces act on this parachutist? Certainly, there is a force of gravity, the weight W , But there is also a force of air ...


Vectors and 2D Motion

www.ux1.eiu.edu/~cfadd/1150/03Vct2D/disp.html

... one-dimensional motion, we often want to know about the instantaneous velocity, the velocity at this moment. That is the average velocity over a smaller and smaller time interval. As before, this instantaneous velocity is often called ...

... is the same as replacing v with  - v! So far we have not mentioned the coordinates y and z, perpendicular to the relative velocity vector. They are not altered at all. That is, y B = y A and z B = z A Now that we have the Lorentz ...

... v = 0.95 c The velocity of particle 2 as seen in the LAB frame is the velocity of M as seen in the "stationary" frame A; that is, v xMA = - 0.95 c And we are looking for the velocity of particle 2 as seen by particle 1. In terms of our ...
