[6] Diagram showing how an exoplanet's orbit changes the position and velocity of a star as they orbit a common center of mass. In many binary stars, the orbital motion usually causes radial velocity variations of several kilometres per second (km/s). As the spectra of these stars vary due to the Doppler effect, they are called spectroscopic ...
AMaRV had an entry mass of approximately 470 kg, a nose radius of 2.34 cm, a forward frustum half-angle of 10.4°, an inter-frustum radius of 14.6 cm, aft frustum half angle of 6°, and an axial length of 2.079 meters. The design was essentially a conical RV with a slice cut off one side to form a flat surface.
Snap, [6] or jounce, [2] is the fourth derivative of the position vector with respect to time, or the rate of change of the jerk with respect to time. [4] Equivalently, it is the second derivative of acceleration or the third derivative of velocity, and is defined by any of the following equivalent expressions: = ȷ = = =.
The term recreational vehicle (RV) is often used as a broad category of motor vehicles and trailers which include living quarters for designed temporary accommodation. [1] Types of RVs include motorhomes, campervans, caravans (also known as travel trailers and camper trailers), fifth-wheel trailers, popup campers, truck campers and Park Model RVs.

An example of a Class C recreational vehicle, recognisable by the extension of the cabin over the cab Motor home Map symbol used by the US NPS to indicate an RV campground. A recreational vehicle, often abbreviated as RV, is a motor vehicle or trailer that includes living quarters designed for accommodation. [1]
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).
