Every week, the readers of our space newsletter, The Airlock, send in their questions for space reporter Neel V. Patel to answer. This week: how to produce artificial Earth-like gravity through ...

In high-intensity laser–matter interactions, including laser-induced particle acceleration, physicists generally want to work ...

Learn the key physics definitions of position, displacement, velocity, and acceleration explained clearly and simply. This quick breakdown helps build a strong foundation for understanding motion in ...

Learn how tension and friction interact when an object moves at constant velocity. This video breaks down the force balance, explains why acceleration is zero, and shows how physics principles apply ...

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 ...
