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 ...

The idea of emergent gravity is still new and requires a lot of assumptions in its calculations to make it work. But if experimental evidence ever proves it real, we would need to totally rewrite the ...

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, ...
