My mind is going around in circles over this. I know that orbital velocity is what a satellite requires to stay in orbit and I know what the equation is but I thought velocity was a vector not a number so shouldn't it be speed and not velocity.

Then I found some sites that talk about tangential velocity as the orbital velocity. Then I found some sites that use m/s for the velocity and others use radians/s for the velocity.

Could anyone give clarification about orbital velocity, speed and tangential velocity as well as a simple example.

Many thanks.
