Revolutions per Second (r/s)

Revolutions per second (r/s) is a unit of angular velocity that measures how many complete rotations or revolutions an object makes in one second. One revolution corresponds to a full 360-degree turn or $2\pi$ radians. This unit is commonly used to describe very fast rotational speeds in machinery, motors, turbines, and other high-speed rotating systems. For example, a motor spinning at 50 r/s completes 50 full rotations every second. Revolutions per second provide a clear and precise measure of rapid rotational motion, useful in physics, engineering, and technology fields where high-speed rotation is involved. It also facilitates easy conversion to other angular velocity units like radians per second or revolutions per minute.

Galileo (Unit) – A Short Note

The galileo (symbol: Gal) is a unit of acceleration used mainly in the field of geophysics, especially gravimetry, which measures the Earth's gravitational field.

One galileo is defined as:

1 Gal = 1 centimeter per second squared (1 cm/s²)

It is a non-SI (non-International System) unit, named after the Italian scientist Galileo Galilei in honor of his pioneering work on gravity and motion.

Because the Gal is a relatively large unit for precise gravity measurements, smaller subunits are often used:

• 
  

  1 milligal (mGal) = 0.001 Gal

  
  
• 
  

  1 microgal (µGal) = 0.000001 Gal

  
  

In practical terms, Earth's surface gravity is about 980 Gal, but variations in local gravity fields (due to terrain, density, etc.) are often measured in milligals or microgals.

The galileo unit is essential in geophysical surveys, oil exploration, and earthquake studies.
