Learn how to calculate the universal gravitational force between two objects! This video explains Newton’s Law of Gravitation, walking you through the formula, units, and a step-by-step example to ...

It's fun to think about how we know stuff. For instance, the sun has a mass of about 2 x 10 30 kilograms. That is such an enormous mass that it's difficult to comprehend. And if it's so difficult for ...

Shini sits down to talk about how Newtonian Gravity is more than a little important. In this episode of Crash Course Physics, Shini sits down to talk about the realities of the apple story and how ...

Gravity is a ubiquitous part of our daily lives — whether we’re being tragically brought to our knees after tripping on the rug or gleefully jumping from a swing’s apex. But despite how common the ...

Gravitational physicists explore the implications of the general theory of relativity, in which gravitation is a consequence of the curvature of space and time. This curvature thus controls the motion ...

Four fundamental forces are known in physics: the weak and strong interactions, and the electromagnetic and gravitational forces. The gravitational force is the weakest of these four. For this reason, ...
