The speed and direction with which an object moves is called its velocity.

Here's a breakdown:

* Speed is how fast an object is moving, measured in units like meters per second (m/s) or kilometers per hour (km/h).

* Direction tells us which way the object is moving, like north, south, east, west, or a specific angle.

Velocity combines both speed and direction. It's a vector quantity, meaning it has both magnitude (speed) and direction.

For example:

* A car traveling at 60 km/h is its speed.

* A car traveling 60 km/h north is its velocity.
