Other Units of Acceleration
Unit is a standard measurement of a physical quantity that are used to express the size or magnitude of any physical quantity in relation to a standard reference. There are different units chosen for the measurement of same physical quantity for its convenient representation in terms of magnitude. Different units of acceleration are discussed as follows:
Feet per Second square
Feet per Second square is an unit of acceleration in FPS system, i.e. Feet (length), Pound (mass), and Second (time). It represents the acceleration in which velocity changes by 1 foot in 1 second. 1 foot is 0.3048 meters.
Thus, 1 ft/s2 is the acceleration in which velocity changes by 0.3048 m/s in 1 second.
Gal Unit of Acceleration
Gal unit of acceleration is 1 cm/s2. It is named after the scientist Galileo Galilei. It is commonly used in measurements related to acceleration due to gravity.
The acceleration due to Earth’s gravity at its surface is taken as 976 to 983 Gal. 1 Gal is equal to 0.01 m/s2. It is same as the unit of acceleration in CGS system.
Standard Gravity
Standard Gravity is the value of acceleration due to gravitational force experienced by an object on Earth’s surface. It is taken as a constant and defined as 9.80665 m/s2. In CGS system, it is 980.665 cm/s2.
Planck Acceleration
Planck Acceleration is the acceleration required for an object which is initially at rest to attain the speed of light in Planck unit time. Planck time is defined as 5.391 x 10−44 seconds. The value of 1 unit of Planck Acceleration is thus obtained as 1051 m/s2.
Unit of Acceleration
Unit of Acceleration is meter per second square or m/s2. Acceleration is the rate at which the velocity of a body changes. The most commonly used units of acceleration are meters per second square (m/s2) and kilometer per hour square (km/h2).
In this article, we will learn the definition of acceleration, the unit of acceleration, units in various systems, sample problems, and frequently asked questions related to the unit of acceleration.
