Acceleration Unit Knowledge

Acceleration Basics

Acceleration is the rate of change of velocity over time. The SI unit is meters per second squared (m/s²). Standard gravity (g) = 9.80665 m/s² is the acceleration due to gravity at Earth's surface.

Common Acceleration Conversions

  • 1 g = 9.80665 m/s² = 32.174 ft/s². 1 Gal = 0.01 m/s² = 1 cm/s² (used in geophysics). 1 ft/s² = 0.3048 m/s². Fighter pilots can withstand 9g momentarily
  • sustained high-g causes blackout.

Standard Gravity (g)

Standard gravity (g₀ = 9.80665 m/s²) is defined by the ISO. It represents the mean gravitational acceleration at Earth's surface. Actual gravity varies from 9.764 m/s² at the equator to 9.834 m/s² at the poles.

Galileo (Gal) in Geophysics

The Galileo (Gal) is a unit used in gravimetry and seismology: 1 Gal = 0.01 m/s² = 1 cm/s². The milligal (mGal) = 10⁻⁵ m/s² is commonly used for gravity surveys, as typical variations across Earth's surface are measured in milligals.

Acceleration in Technology

Rocket acceleration: Saturn V achieved peak 40 m/s² (~4g). Car 0–100 km/h in 4s ≈ 7 m/s² (~0.7g). Smartphones contain accelerometers measuring ±2g to ±16g. High-speed centrifuges can exceed 100,000g.
