When an object spins, its center of mass and angular momentum enter a tug-of-war that can lead to impossible motion. From falling tennis rackets flipping midair to spinning wheels that rise on their ...

In physics, momentum refers to the tendency of an object to continue moving in a particular direction due to its mass and velocity. The velocity, or direction, of momentum can change due to an ...

Introduction: Athletic performance in competitive ski jumping is evaluated based on the aggregate scores of the jump distance and flying style. However, an understanding of how angular momentum ...

One of the most notable aspects about our planet—if observed from the outside—is that it spins. Earth’s spin defines our days, setting the fundamental rhythm of life on our world. The moon spins, too.

Schematic of a single photon with zero angular momentum (green) splitting into two photons (red) with either zero or opposite angular momenta (sketched through the spatially varying color), which adds ...
