Physics, especially the part about forces and motion, often feels like a maze of confusing concepts and formulas. If you’ve ever stared at a problem about an object moving or a force acting and ...

Given a particle in Euclidean space, a central force is a force that points toward or away from the origin and depends only on the particle’s distance from the origin. If the particle’s position at ...

Gravity is the force of action between two objects. It’s called a natural force because it acts at a distance rather than needing to be in contact. Gravity is the force that holds us down on Earth and ...

Keep on moving – or not! Explore Newton’s First Law of Motion! Keep on moving – or not! Explore Newton’s First Law of Motion! Dr. Rob and the Crew use bowling balls, beads, and bottles to investigate ...

A team led by UNIGE has shown that the most mysterious component of our Universe follows the laws of classical physics, though some doubts still remain. Does dark matter obey the same physical laws as ...

Does dark matter follow the same laws as ordinary matter? The mystery of this invisible and hypothetical component of our ...

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 ...

For hundreds of years, we have been told what Newton’s First Law of Motion supposedly says, but recently a paper published in Philosophy of Science (preprint) by [Daniel Hoek] argues that it is based ...
