By understanding work and energy concepts in sports, athletes can improve speed, endurance, power, and accuracy while also ...

The planet’s rotation fluctuates as it travels around the sun, and measurements suggest we’re losing more than a millisecond ...

The rotation of the pendulum’s plane of oscillation is also investigated and I show that the angular displacement of this plane depends essentially on the initial conditions, predicting that even if a ...

The Great Rotation out of the U.S. toward other markets is still in motion, says strategist By Jules Rimmer Last Updated: June 27, 2025 at 5:32 a.m. ET First Published: June 27, 2025 at 5:30 a.m. ET ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Ever swung on a playground swing? That's a pendulum in motion! On today's MOSI Monday, we're looking at pendulum and angular momentum!

This intends to redirect the rotational motion away from the head in certain angled impacts, thereby lowering the risk of injuries like concussions and TBIs.

Alongside bearings, which reduce friction, motors, and gears, the average humanoid robot relies on dozens of screws—key components that convert the rotational motion produced by a motor into ...

An innovative new combustion engine eliminates half the guts of a traditional engine, and uses a fascinating internally rotating piston and sleeve arrangement, making it lighter, simpler and more ...

Previously, we obtained kinematic parameters for operating two cervical spine rotation manipulations under motion capture monitoring and compared parameters such as angular displacement of the ...
