Repetitive behaviors can include hand-flapping, toe-walking, doing what many parents call a happy dance. Can also be aimlessly roaming around the room in constant motion without any actual obvious ...

Constant Force and Constant Motion I see this problem all the time. The idea that if you apply a constant force on an object, it should move at a constant speed.

This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to ...

Our motion perception is remarkably well tuned to detect small changes in speed and direction. For example, soccer goalkeepers need to precisely judge the speed, direction, and curvature of an ...

Zero-point motion mapped in 3D “The molecule is not rigid, but in constant motion due to quantum fluctuations,” said Markus Ilchen, a lead author of the study.

At room temperature, micron-sized sheets of freestanding graphene are in constant motion, even in the presence of an applied bias voltage. University of Arkansas researchers collecting the ...

Newton’s Second Law of Motion states, “The force acting on an object is equal to the mass of that object times its acceleration.” ...

President Donald Trump seems to have spent his first 97 days in near-constant motion. If he’s not tweeting about something or hosting members of Congress at the White House, he’s huddled with ...
