About Acceleration

Acceleration is the velocity change rate over time, typically expressed in meters per second squared (m/s²). It is a vector quantity with magnitude and direction.

• Meter per second squared (m/s²) – SI unit of acceleration.
• Foot per second squared (ft/s²) – Imperial unit of everyday use.
• Galileo (Gal) – Geophysics application (1 Gal = 0.01 m/s²).
• Standard gravity (g) – Earth's gravity acceleration (9.80665 m/s²).
• Mile per hour squared (mi/h²) – Used in transportation dynamics.
• Knot per second (kn/s) – Used in maritime and aviation.
• Planck acceleration – Theoretical unit from quantum physics.
• Lunar gravity (gₘ) – Surface gravity of the Moon (~1.62 m/s²).
• Solar gravity (gₛ) – Surface gravity of the Sun (~274 m/s²).

Acceleration Units

Acceleration is one of the fundamental concepts of physics that describe how quickly the velocity changes with time. In all contexts—scientific, engineering, and practical—different units are used around the globe to quantify it.

• Meter per second squared (m/s²): The most commonly used SI unit, describing the acceleration of an object gaining one meter per second in velocity every second. Standard in physics, engineering, and science.
• Kilometer per hour squared (km/h²), Centimeter per second squared (cm/s²), Millimeter per second squared (mm/s²): Used in everyday applications such as vehicle dynamics to express smaller accelerations in a more comprehensible format.
• Standard gravity (g): Acceleration due to gravity on Earth's surface, approximately 9.80665 m/s². Commonly used in aviation, aerospace, and biomechanics. Related concept: G-force (gf).
• Galileo (Gal): Used in the CGS system, along with subunits milligalileo (mGal), centigalileo (cGal), and decigalileo (dGal), especially in geophysics and gravimetry.
• Foot per second squared (ft/s²), Inch per second squared (in/s²): Traditional imperial units used in engineering and transportation sectors.
• Mile per hour squared (mi/h²), Mile per second squared (mi/s²): Applied in automotive and aviation contexts.
• Knot per second (kn/s), Knot per hour (kn/h): Units tailored to velocity changes in nautical miles, used in sea and air navigation.
• Planck acceleration: A theoretical unit based on fundamental constants, used in advanced physics.
• Earth gravity (average), Moon gravity (lunar g), Solar gravity (solar g): Used in planetary science to describe gravitational fields of celestial bodies.

All these measurements together provide a wide-ranging and versatile system to express acceleration across different scales, scientific disciplines, and environments.
