Consider the following physics problem. An object with a mass of 1 kg and a velocity of 1 m/s in the x-direction has a net force of 1 Newton pushing on it (also in the x-direction). What will the ...

I saw it again. This time it was an introduction to an interesting online look at introductory physics. I was excited---but then, I wasn't so excited. Right there in the first video they talked about ...

In 1687, Sir Isaac Newton published his groundbreaking book, which described the three laws of motion and redefined the way the world looked at physics and science. These laws also work well as an ...

A ripe apple falling from a tree has inspired Sir Isaac Newton to formulate a theory that describes the motion of objects subject to a force. Newton's equations of motion tell us that a moving body ...

Several years back, I had the pleasure of watching Dan Cobley’s TED Talk, “What physics taught me about marketing.” In this talk, Cobley illustrates how physics and the scientific method can be ...

DIY Science Time is available to stream on pbs.org and the free PBS App, available on iPhone, Apple TV, Android TV, Android smartphones, Amazon Fire TV, Amazon Fire Tablet, Roku, Samsung Smart TV, and ...

For years, a fringe theory challenging Isaac Newton’s Laws of Motion, known as Quantized Inertia (QI), has been used in an attempt to create a propellant-less engine. Now, the idea will get its ...
