The pendulum’s natural motion is given by the laws of gravity (Newtonian gravity, in this case). But the silicon disc is an excellent mirror: it can be pushed around by light.

The detector is essentially a pendulum—a molybdenum ring hanging on an ultrathin tungsten fiber—that feels the gravitational tug of two rotating molybdenum disks below. The disks are positioned so ...

In just a matter of days, Hersheypark-goers will get the chance to ride to the park's newest attraction—Twizzlers Twisted Gravity. Once the pendulum attraction opens on Saturday, May 24, it will ...

This is because the swinging motion of a pendulum is due to the force of gravity generated by the earth's size. Other factors, including a pendulum's length, can also affect its motion.
