Unit of Velocity

Introduction:

The velocity of an object is usually defined as the rate of displacement that a particle or an object undergoes within a span of time. Velocity is stated to be a physical vector quantity meaning both direction and magnitude have to be considered to define it.

However, speed and velocity should not be confused. There is a great distinction between the two; for example, velocity tells us about the object’s speed and in which direction it is moving, while speed gives us an idea of how fast the object is moving. While it is important to remember this fact, we will study the unit of velocity in this article.

What is the SI Unit of Velocity?

First, let us take a look at the formula of velocity

• V is the velocity
• s is displacement
• t is the time taken

If we remember, displacement is usually addressed in metres, and the time taken is depicted in seconds. Therefore, velocity is expressed in metres/second or m/s.

The SI unit of velocity is metre per second (m/s).

Alternatively, the velocity magnitude can also be expressed in centimetres per second (cm/s).

Some Other Velocity Units

Some of the other units that identify velocity are:

• Kilometres per hour
• Knot (unit)
• Feet per minute
• Foot per second
• Metre per hour
• Miles per hour
• Inch per second
• Speed of light
