Another theory held that the forces between two particles falls off exponentially in direct relationship to the distance between two particles and that the factor by which it drops is not dependent on ...

Explore the difference between calculated forces and constraint forces in this physics-focused video! Learn how to identify, compute, and distinguish between the forces acting on objects, including ...

A new study suggests subatomic particles called muons are breaking the laws of physics. This may mean a mysterious force is affecting muons, which would make our understanding of physics incomplete.

A subatomic particle called the muon is wobbling far more than leading physics models can explain. Its unusual behavior could be evidence of a fifth force of nature or a new dimension. Scientists ...

There may be a fifth fundamental force of the universe that we haven’t documented yet — and, according to new research, our best bet of uncovering it may not lie in deep space, but in objects ...
