Newton’s First Law: Inertia An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force. Newton’s laws together with Kepler’s Laws explained why planets move in elliptical orbits rather than in circles.īelow is a short movie featuring Orville and Wilbur Wright and a discussion about how Newton’s Laws of Motion applied to the flight of their aircraft. In 1686, he presented his three laws of motion in the “Principia Mathematica Philosophiae Naturalis.”īy developing his three laws of motion, Newton revolutionized science. He developed the theories of gravitation in 1666 when he was only 23 years old. Sir Isaac Newton worked in many areas of mathematics and physics. Whenever one object exerts a force on another object, the second object exerts an equal and opposite on the first.

The acceleration of an object depends on the mass of the object and the amount of force applied.An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.(* Convert Mathematica notebooks to PDFs *) #!/usr/local/bin/MathematicaScript -script Save the following code as nb2pdf, make it executable and place it the directory with the files you want to convert or somewhere in your path. Here's a solution in the form of a Mathematica script - it can easily be turned into a Notebook or package file. This means that you could either make a notebook to do the conversion or call the frontend from the command line.

To print or convert it, you first need to open it andĪ naive attempt to open a notebook from the Mathematica command line yields the error FrontEndObject::notavail In:= NotebookOpenĪ front end is not available certain operations require a front end. Basically, there is no way to convert Mathematica notebooks into PDFs without invoking the frontend.
