Lockheed P-38 Lightning - Aviation History

The fastest of the Lightnings was the P-38J with a top speed of 420 mph, and the version produced in the greatest quantity was the "L", of which 3,735 were built by Lockheed and 113 by Vultee. After the "L" model was introduced, just about all of the mechanical problems disappeared and the P-38 became a great combat airplane.

Speed of the Earth - ThoughtCo

Everything is cyclical, even the speed of the rotation of the Earth, which geophysicists can measure precisely, in milliseconds. Earth's rotation tends to have a five-year span, where it slows down before speeding back up again, and the final year of the slowdown correlates with an uptick in earthquakes around the world.

Rotational Kinetic Energy | Boundless Physics

In the rotating system, the moment of inertia takes the role of the mass and the angular velocity takes the role of the linear velocity. As an example, let us calculate the rotational kinetic energy of the Earth (animated in Figure 1 ). As the Earth has a period of about 23.93 hours, it has an angular velocity of 7.29×10 −5 rad/s.

How to Convert RPM to Linear Speed | Sciencing

Apr 24, 2017 · Linear speed measures the actual distance traveled, often in feet per minute. Because a rotation always covers the same distance, you can convert from rpm to linear distance if you can find the distance per rotation. To do so, all you need is the diameter of the rotation.
