Speaker one We’ve been using Sir Isaac Newton’s theories for hundreds of years and still use his equations today. Now, how can we test Newton’s second law using equipment found in our laboratory?

Driving a spacecraft around a planet isn’t anything like driving on a planet. A physicist explains orbital navigation.

Let's explore the fascinating world of forces, particularly how they interact and combine using a force table and the principle of vector addition. This is a cornerstone concept in physics, providing ...

THE colder, darker months can quietly wreak havoc on our skin – and our lifespans. Wrinkles become deeper, dryness sets in, ...

The net force is the vector sum of all individual forces acting on an object. It represents the overall effect of all forces ...

The investigator in Syria had made the drive perhaps a hundred times, always in the same battered truck, never with any cargo. It was forty miles to the border, through eleven rebel checkpoints, where ...

In this video, we explore Albert Einstein's theory of general relativity, focusing on his insights into gravity and ...

Scientists have discovered that dark matter, the universe's most mysterious "stuff," obeys gravity on vast cosmological scales. This could help to dismiss the possibility of a fifth fundamental force ...

A new computational method now makes it possible to calculate the forces between large molecules with unprecedented accuracy.

ALMA reveals that gravity reorients magnetic fields in 17 young clusters, aligning them as gas collapses and accelerating ...

Ribonucleic acid (RNA) is one of life's most versatile molecules, with roles going far beyond being a messenger of genetic ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
