The linear distance or the extent of the movement from the center point to one side.
A Dutch mathematician and scientist who designed a workable mechanism for a pendulum clock.
Center of mass
The middle of an object.
A bob, or an object, at the end of a pendulum.
The ability to do work and to cause motion.
A balanced pattern on each side of a fixed point; pendulum paths are symmetrical because the pattern is identical on either side of the center.
An object at rest, or an object moving, will remain at rest or moving until acted upon by another force (such as gravity); resistance to motion, action, or change.
A suspended weight that can be set in motion to swing back and forth from a fixed point. A simple device whose motion depends on gravity.
Things that remain unchanged in an experiment or process.
Coupled pendulums
Two separately hung pendulums that are linked together below their pivot points.
A weight suspended at the end of a pendulum in such a way that it is free to swing back and forth.
Coupled pendulums
Two separately hung pendulums that are linked together below their pivot points.
A round trip; one swing out and back of the pendulum.
A force that acts to resist motion (movement) between two surface.
An English mathematician, scientist, and philosopher. Major works include his theories on gravity, color, and differential calculus. In the pendulum experiments, Newton's laws of motion can be observed.
The duration of a single cycle; the time that a pendulum takes to complete one cycle (one swing out and back).
Pullback distance
A term that refers to the distance between the center point of a bob and its point of release.
The number of waves or complete cycles per unit of time; the number of cycles (round trips) the pendulum makes in a set period of time (usually one minute).
A cycle.
Something in an experiment that changes; an experimental factor that is supposed to change so the scientist can determine if a certain action is caused by that variable.
A force that pulls objects toward the center of the earth, measured by weight; mutual attraction between all masses in the universe.
Designs consisting of repeated lines and shapes.
Round trip
A cycle; one swing of a pendulum out and back.
An Italian scientist of astronomy and physics. He believed that discovering accurately how natural phenomena occured was more important to scientific advancement than reaching conclusions.
Stick pendulum
A type of pendulum that has a stick instead of a string; for example, a grandfather clock has a stick pendulum.
An idea not proved, but assumed to be possible. An assumption used as a basis for action; an "educated guess."
