In this video, we derive the speed required for a stable circular orbit around Earth using Newton’s law of gravitation and centripetal force. You’ll see how orbital speed depends on radius, why low ...

In this video, we derive the catenary curve using physics and calculus, explaining how a hanging cable reaches equilibrium under gravity. Step-by-step reasoning connects forces, differential equations ...

Bolstered by a $7.1M seed Round and $1.25M Air Force contract, the company proves that batteries can take any shape, from the factory floor to the tac ...

Researchers in Germany argue that a modified theory of gravity could explain universal expansion, removing dark energy from ...

The standard explanation has been dark energy, an invisible force added into the equations to make the math work. But now, an ...

After rocking a pixie for fall, Emma Stone is back in her bob era. Her hairstylist, Mara Rozak, used her RŌZ Air Thickening ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...
