This was for the xcomponent of the velocity, so we can write that explicitly, Distances in the y and zdirections are not affected, but time is affected. So the velocity components in the y and zdirections are ...
Speed and Velocity www.ux1.eiu.edu/%7Ecfadd/3050/Ch03LinearMotion/Speed.html ... 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 ... onedimensional 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 ...

Special Relativity www.ux1.eiu.edu/~cfadd/1160/Ch27SpRl/ApLrntz.html ... at our leisure, we can measure the distance between these marks. Consider a meterstick at rest in the B frame, moving at velocity v with respect to the A frame. The two ends of the meter stick are marked by "events" . This may be exploding ...
Special Relativity www.ux1.eiu.edu/~cfadd/1160/Ch27SpRl/SpTm.html ... postulate of Special Relativity: All the laws of Physics are the same for all observers moving with consant relative velocity. An important corollary: All observers in inertial frames measure the same value for the speed of light (in ...
Special Relativity www.ux1.eiu.edu/~cfadd/1160/Ch27SpRl/Lrntz.html ... 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 ...
PHY1160C, Principles of Physics II www.ux1.eiu.edu/~cfadd/1160/Ch27SpRl/Ch27Hmwk.html ... 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 ...
