For this project I show how to make make a pendulum wave, an interesting science/physics experiment where a series of pendulums is measured so that each one moves slightly faster than the one before ...

There’s a rift in reality—an invisible border that separates two utterly different realms. On one side lies our everyday world, where things obey commonsense rules: objects never occupy more than one ...

PROF. GREENHILL gives currency to quite an erroneous idea, in last week's NATURE (p. 50). He says “in the Foucault experiment of the pendulum which shows the rotation of the earth, the slightest ...

In the months following Jean Bernard Leon Foucault's early 1851 demonstration in Paris of the earth's diurnal rotation with a vibrating pendulum, members of the entire scientific community, as well as ...

Experiment with three pendulums that are 1-ft, 2.25-ft, and 9-ft long. Determine how many times the 2.25-ft and 9-ft pendulums swing during the time it takes the 1-ft pendulum to swing 30 times. Find ...

The 1 kg pendulum is held up to the demonstrator's face and released. Because of conservation of energy, the ball will not swing higher than the height at which it was released (in fact, because ...
