There are quite a few fundamental constants. These are things like the speed of light (c) the charge on an electron (e), and the Planck constant (h). These constants are determined with some type of ...

As we know that force is necessary to produce motion in a body. If any object falls from some height towards the earth, therefore a force must be acting on it. This force is due to the attraction ...

The Force is With You? You may have heard that gravity isn’t a force. This is true. Gravity is not a force; however, this truth leaves us with a number of questions. For example, we’re commonly told ...

Gravity, despite its pervasive influence, is the weakest fundamental force, easily overcome even by simple actions like lifting a pencil. While achieving and maintaining orbit requires significant ...

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 ...

Physicist Markus Aspelmeyer vividly remembers the day, nearly a decade ago, that a visitor to his lab declared the gravitational pull of his office chair too weak to measure. Measurable or not, this ...

What is gravity? Is it a force, a pseudo force, or something else? This question is being debated vigorously by physicists since 2015, the 100th anniversary of Einstein's Theory of General Relativity.

This story was originally published by Inside Science News Service. Henry Cavendish was an odd man. He never addressed strangers directly and was petrified of women. He had a staircase built into the ...

When you travel through the Universe, it isn't just a free ride through empty space. Although you might not think about it very often, there are forces arising from the presence of everything else, ...
