ABCya.com, L.L.C. (also stylized as ABCya!) is a website that provides educational games and activities for school-aged children. The games on the website are organized into grade levels from pre-kindergarten to Sixth grade, as well as into subject categories such as letters, numbers, and holidays. Many of the games meet standards associated ...
Gravitational acceleration. In physics, gravitational acceleration is the acceleration of an object in free fall within a vacuum (and thus without experiencing drag ). This is the steady gain in speed caused exclusively by gravitational attraction. All bodies accelerate in vacuum at the same rate, regardless of the masses or compositions of the ...
Artificial gravity is the creation of an inertial force that mimics the effects of a gravitational force, usually by rotation. [ 1] Artificial gravity, or rotational gravity, is thus the appearance of a centrifugal force in a rotating frame of reference (the transmission of centripetal acceleration via normal force in the non-rotating frame of ...
The first direct observation of gravitational waves was made on 14 September 2015 and was announced by the LIGO and Virgo collaborations on 11 February 2016. [ 3][ 4][ 5] Previously, gravitational waves had been inferred only indirectly, via their effect on the timing of pulsars in binary star systems. The waveform, detected by both LIGO ...
The gravitational redshift of a light wave as it moves upwards against a gravitational field (produced by the yellow star below). The effect is greatly exaggerated in this diagram. In physics and general relativity, gravitational redshift (known as Einstein shift in older literature) [ 1][ 2] is the phenomenon that electromagnetic waves or ...
Beyond the Standard Model. In physics, Kaluza–Klein theory ( KK theory) is a classical unified field theory of gravitation and electromagnetism built around the idea of a fifth dimension beyond the common 4D of space and time and considered an important precursor to string theory. In their setup, the vacuum has the usual 3 dimensions of space ...
pc ⋅ M⊙−1 ⋅ ( km / s) 2. The gravitational constant G is a key quantity in Newton's law of universal gravitation. The gravitational constant is an empirical physical constant involved in the calculation of gravitational effects in Sir Isaac Newton 's law of universal gravitation and in Albert Einstein 's theory of general relativity.
