The unit for tangential velocity is the same as the unit for any velocity, which is meters per second (m/s).

Here's why:

* Tangential velocity is the velocity of an object moving along a circular path.

* Velocity is a vector quantity, meaning it has both magnitude (speed) and direction.

* Speed is the rate at which an object changes its position, and is measured in units of distance over time, like meters per second.

While tangential velocity is specifically referring to the velocity along a circular path, it still fundamentally represents the rate of change of position, and therefore its unit remains the same as for any other velocity.
