Along with gravimeters and torsion balances, pendulums can be used to measure gravitational force. The period oscillation of the pendulum can be used to measure gravitational acceleration, and in turn ...

The Foucault Pendulum illustrates the rotation of the earth. It is not constrained to stay in a fixed plane like a clock pendulum, but instead its ordinary pendulum motion is free to change direction ...

While it would be awesome for people to be able to live in space, a "weightless" environment poses some serious challenges. Humans function best on Earth’s surface, where they are affected by a ...

Gravity might feel strong if you drop a bowling ball on your feet, but is in fact the weakest force. Compare it to electromagnetism: the pull of all the Earth’s gravity can’t stop you from picking up ...
