Three thought experiments involving “demons” have haunted physics for centuries. What should we make of them today?

In this video, we explain the Work-Energy Principle and how to determine the work done on an object. Learn how force, displacement, and the angle between them come into play when calculating work, and ...

Make sure your angles are in units of radians (not degrees), where 2π radians = 360 degrees. But after that you will get the ...

The Quetzalcoatlus northropi was the largest flying animal that ever lived. The huge pterosaur existed during the Late ...

By establishing a larger principle for how things shatter, certain energy-intensive tasks could gain an advantage.

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is ...

"Learn how to calculate the moment of inertia for both hollow and solid spheres in this physics tutorial! We’ll walk you through the process of finding the moment of inertia for each type of sphere, ...

Scenario: Car A is traveling at a constant speed of 20 m/s around a circular track with a radius of 50 meters. Car B is ...

Archimedes’ legendary “Eureka!” moment is often told as a simple bathtub story, but the real drama may lie in his audacious ...

Confusing Momentum with Kinetic Energy: While both are related to motion, momentum is a vector, and kinetic energy is a ...

Professor K.T. Ramesh's How to Stop an Asteroid course introduces first-year Johns Hopkins undergrads to both the engineering ...

The same pulling force that causes “tears” in a glass of wine also shapes embryos. It’s another example of how genes exploit mechanical forces for growth and development. Sip a glass of wine, and you ...
