You see this all the time in textbooks: This is often described as "the acceleration due to gravity". Is this really the best thing to call this? No. A better name would be "the local gravitational ...

According to legend, Galileo dropped weights off of the Leaning Tower of Pisa, showing that gravity causes objects of different masses to fall with the same acceleration. In recent years, researchers ...

Every week, the readers of our space newsletter, The Airlock, send in their questions for space reporter Neel V. Patel to answer. This week: how to produce artificial Earth-like gravity through ...

Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm afternoon, he saw an apple fall from a tree and wondered why it should fall down ...

AN absolute determination of the acceleration due to gravity at a site in the National Physical Laboratory has recently been completed. It is the first to be made by timing the symmetrical up-and-down ...

I had an interesting thought, spurred on by a discussion I ran across online about firing guns in space. Apparently, smokeless powder contains its own oxidizer and so you could shoot normal firearms ...

As the story goes, mathematician Sir Isaac Newton was sitting in an orchard after supper when he saw an apple fall from a tree. He wondered why apples always fall straight to the ground, instead of ...
