Which formula can be used to find the tangential speed of an orbiting object?
1 answer:
The tangential speed of an orbiting object is
Explanation:
The tangential speed of an orbiting object is defined as the ratio between the distance covered in one revolution and the period of revolution:
where
d is the distance covered during one period
T is the orbital period
However, the distance covered during one period is the circumference of the circle:
where
r is the radius of the circle
Substituting the 2nd equation into the 1st equation, we find:
So, this is the final expression for the tangential speed of an orbiting object.
