The radial velocity of a star or other luminous distant objects can be measured accurately by taking a high-resolution spectrum and comparing the measured wavelengths of known spectral lines to wavelengths from laboratory measurements. A positive radial velocity indicates the distance between the objects is or was increasing; a negative radial ...
Relative velocities between two particles in classical mechanics. The figure shows two objects A and B moving at constant velocity. The equations of motion are: = +, = +, where the subscript i refers to the initial displacement (at time t equal to zero).
A mobile laboratory is a laboratory that is either fully housed within or transported by a vehicle such as a converted bus, RV, or tractor-trailer. [1] [2] Such vehicles can serve a variety of functions, including: Science education; Science research; Air, water, and soil analysis and monitoring; Biosafety

This new RV was the Mk-6 which used a non-metallic ablative TPS, a nylon phenolic. This new TPS was so effective as a reentry heat shield that significantly reduced bluntness was possible. [citation needed] However, the Mk-6 was a huge RV with an entry mass of 3,360 kg, a length of 3.1 m and a half-angle of 12.5°. Subsequent advances in ...
The Schuster Laboratory, University of Manchester (a physics laboratory) A laboratory (UK: / l ə ˈ b ɒr ə t ər i /; US: / ˈ l æ b r ə t ɔːr i /; colloquially lab) is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed.

In physics, the laboratory frame of reference, or lab frame for short, is a frame of reference centered on the laboratory in which the experiment (either real or thought experiment) is done. This is the reference frame in which the laboratory is at rest.
