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 ...

Gravity is, at heart, a mystery. Yes, we can talk about curvature of space-time and perhaps make analogies with stretched rubber sheets. But we don’t know why mass causes space-time to curve. To put ...

The answer is yes. Yes, you can get a value of pi using a pendulum. Well, you need a few other things. Of course, this is the experimental part of my previous post on the connection between pi and the ...

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 ...

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 ...
