Everyone loves perpetual motion machines. They are a representation of the highest level of creativity in finding loopholes in the laws of physics. Let's take a look at this one. What is a perpetual ...

Isaac Newton would never have discovered the laws of motion had he studied only cats. Suppose you hold a cat, stomach up, and drop it from a second-story window. If a cat is simply a mechanical system ...

Researchers have observed a molecule in the first instants after it has absorbed light and tracked the coordinated motion of ...

Equation of cat motion. Credit: Anxo Biasi Starting from this formula, and through the analysis of feline motion, it is possible to show how the equations themselves are constructed. "The work ...

Why do things fall? It’s about force and motion. Find out more in this Science Trek short. A force is basically a push or a pull. Forces like gravity, inertia, and momentum affect everything. On this ...

In physics, motion is a change in position of an object with respect to time and its reference point. Motion is typically described in terms of displacement,velocity, acceleration, and time. Motion is ...

Watch bouncing balls move and rebound, showcasing their motion and changing trajectories. #BouncingBalls #Motion #Physics ...

Isaac Newton would never have discovered the laws of motion had he studied only cats. Suppose you hold a cat, stomach up, and drop it from a second-story window. If a cat is simply a mechanical system ...

We solve for centripetal acceleration, centripetal force, and tangential velocity. In this Closer Look segment on circular motion, we investigate circular motion and solve for centripetal acceleration ...
