According to Kepler's second law, the "areal" type of this quantity for a planet is constant using the sun as the origin.
According to Kepler's second law, the "areal" type of this quantity for a planet is constant using the sun as the origin. Dividing Planck's constant by the product of mass and this quantity yields the de Broglie wavelength. The phase type of this quantity for a wave is defined as the angular frequency of the wave divided by the wavenumber. When the sum of the drag force and buoyancy equals the downward force of gravity, the terminal type of this quantity is achieved. For 10 points, name this physical vector quantity defined an object's rate of positional change.
