Momentum as a Vector Quantity. Momentum is a vector quantity.As discussed in an earlier unit, a vector quantity is a quantity that is fully described by both magnitude and direction. To fully describe the momentum of a 5-kg bowling ball moving westward at 2 m/s, you must include information about both the magnitude and the direction of the bowling ball.(Public domain.) The time, location, and magnitude of an earthquake can be determined from the data recorded by seismometer. Seismometers record the vibrations from earthquakes that travel through the Earth. Each seismometer records the shaking of the ground directly beneath it. A Magnitude is the measure of brightness of a celestial object. It is a logarithm scale that is used to determine levels of brightness between other stars. The ratio of apparent brightness between two stars is: There are actually two types of Magnitude: apparent and absolute. Apparent magnitude is the how bright a star looks from Earth.

The term absolute magnitude usually refers to the absolute visual magnitude, Mv of the star, even though the term ‘visual’ really restricts the measurement of the brightness to the wavelength range between 4,000 and 7,000 Angstroms. To convert the observed brightness of a star (the apparent magnitude, m) to an absolute magnitude, we need to ... Absolute Magnitude. Absolute Magnitude: the apparent magnitude that a star would have if it were, in our imagination, placed at a distance of 10 parsecs or 32.6 light years from the Earth. The Distance Modulus. From the definitions for absolute magnitude M and apparent magnitude m, and some algebra, m and M are related by the logarithmic equation.
