The Radial Acceleration calculator computes the radial or centripetal acceleration (arad) of an orbiting body given the period, T, and the radius, R.
INSTRUCTIONS: Choose your preferred units (e.g. milliseconds or years) and enter the following:
The calculator computes the centripetal acceleration (arad) in meters per second. This can be automatically converted to other acceleration units (e.g. feet / meters squared) via the pull-down menu.
