Answer: tangential velocity
The tangential velocity is the velocity the body presents at a given moment of time when describing a circular movement, taking into account its direction, as well as the radius by which it is traveling in a particular fraction of its trajectory.
To calculate tangential velocity, it is possible to take the <u>angular velocity</u> as a reference, nevertheless it is necessary to understand that it can be <u>constant</u>, while the tangential velocity can vary at each step, given the alterations of the path.
This is possible because movement of a satellite around the planet Earth is a good example of uniform circular motion, which is characterized by the movement of a body describing a circumference of a given radius with constant speed.
Therefore in this movement the velocity has a constant magnitude, but its direction varies continuously.
