velocity

What is velocity?

Velocity is the rate at which an object changes its position in a specific direction. It is a vector quantity, meaning it has both magnitude (speed) and direction.

What is the formula for calculating average velocity?

\text{Average Velocity } (\vec{v}) = \frac{\text{Displacement } (\Delta \vec{x})}{\text{Time } (\Delta t)}

How does velocity differ from speed?

Speed is a scalar quantity that only describes how fast an object is moving (magnitude), while velocity is a vector quantity that describes both how fast an object is moving and in what direction.

What are the standard SI units for velocity?

The standard SI unit for velocity is meters per second (m/s).
