Rocket Science equations Slideshow: A math/physics lesson

In my recent blog, NASA: It’s Rocket Science, I asked readers to try to identify NASA’s rocket science equations. See the image below:

Now here are the answers explained below—this IS Rocket Science! (Excuse my back):

And the following is what this all means:

Line 1 and 2, Escape velocity: Escape velocity is the speed at which an object must travel in order to break free of a planet or moon’s gravitational force. So, for a spacecraft leaving the Earth, the velocity would need to be 11 km/s (7 miles/s) which translates to 40,000 km/h (25,000 m/h)

Line 3, Determining a space vehicle’s orbit: when a spacecraft reaches enough speed to attain escape velocity, its orbit becomes parabola. If it moves faster than escape velocity, the orbit becomes a flattened curve, or hyperbola. When a spacecraft leaves Earth orbit, it will travel in a hyperbolic orbit. See the figures below:

    @gsalazar—the best way to get the slides is to use the print function at the top of the article. Sorry—It is a bit tedious, but I cannot provide the original slides since they are property of the magazine.

     

    I'm glad you like the article
