Understanding Velocity

Velocity describes the rate of change of displacement with respect to time. Unlike speed, velocity is a vector quantity, meaning it has both magnitude and direction.

Common Velocity Conversions

  • 1 m/s = 3.6 km/h
  • 1 mph = 1.609 km/h
  • Speed of sound = 343 m/s
  • Speed of light = 299,792,458 m/s

Frequently Asked Questions

What is the formula for velocity?

Velocity = Distance / Time (v = d/t). Speed is the magnitude of velocity.

What is the difference between speed and velocity?

Speed is a scalar quantity (just magnitude), while velocity is a vector (magnitude + direction).

What are the units of velocity?

The SI unit is meters per second (m/s). Other common units include km/h and mph.
