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 ...

"Traditional atom interferometers can only measure acceleration in a single dimension, but we live within a three-dimensional world," said Kendall Mehling, a co-author of the new study and a graduate ...

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 ...

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.
