Engeineers and meteorologist examine the damage done by a tornado to estimate its peak wind speed.
The tornado is then assigned a rating on the Enhanced Fujita Scale from EF0 (weakest) to EF5 (strongest) based on that information.

A tornado is often described as a "force of nature" but in physics it is not a distinct force. Several forces are in operation in and around a tornado.
The Highest wind speed ever recorded in a tornado was 302 mph (some sources say 318 mph) in the F5 tornado that struck Moore and Bridgecreek Oklahoma on May 3, 1999. This tornado is sometimes referred to as the Oklahoma City tornado
