This is a requested post. Clearly, I do requests. The idea here is that I am going to give all the details needed to determine the equation of motion (and then model it) for a basic pendulum. Warning: ...

Although it's not always so simple to set up, a ballistic pendulum is a perfect tool for introductory physics. The basic idea is to take something that shoots an object (we use a ball launcher, but it ...

At the Houston Museum of Natural Science they recently made a disturbing discovery: their Foucault pendulum had stopped swinging for the first time since its installation in the 1970s. (Video, ...

You've probably seen the famous pendulum demonstration—the one where the physics professor puts a bowling ball on a rope, holds it by her head, and lets it go, knowing it won't have enough energy to ...

The first Foucault’s pendulum I ever saw was at the Franklin Institute in Philadelphia, the city where I was born. The pendulum hung in a stairwell. Its wire was attached to the ceiling four stories ...

For the first time, researchers have measured the lifetime of an excited state in the nucleus of an unstable element. This is a major step toward a nuclear clock that could keep even better time than ...
