Imagine you want to study what happens when an object accelerates. Oh, this is way before any of that internet stuff—also, no computers or electronics. In fact, let's say it's the year 1780. What do ...

You're going at the speed limit down a two-lane road when a car barrels out of a driveway on your right. You slam on the brakes, and within a fraction of a second of the impact an airbag inflates, ...

Physicists have used a cloud of atoms chilled down to incredibly cold temperatures to simultaneously measure acceleration in three dimensions - a feat that many scientists didn't think was possible.

Accelerometers are essential sensors used in a wide range of applications including shock and vibration testing, car safety systems, and today's hand-held consumer devices. Generally, they sense the ...

This force will cause the cart to accelerate—in this case, to the left, or the opposite way it was heading, which is why it slows down during impact and even reverses direction. But what is the ...

Scientists have taken lasers beyond light and into the realm of sound, creating a breakthrough “phonon laser” that ...

The iPhone 3G, with its accelerometers and GPS chip, has spawned a unique category of programs in the App Store: automobile performance measurement tools. These programs use the iPhone’s GPS chip to ...

Addressing the increasing demand to accurately measure acceleration in smaller navigation systems and other devices, researchers have developed an accelerometer a mere millimeter thick that uses laser ...

In a new study, physicists at the University of Colorado Boulder have used a cloud of atoms chilled down to incredibly cold temperatures to simultaneously measure acceleration in three dimensions—a ...
