What is the physics of swinging?
Swings work by converting potential energy into kinetic energy, then kinetic energy back into potential energy, over and over again. The kinetic energy is the fast part of swinging; it’s the speed you have as you rush back and forth. Potential energy is the high part of swinging.
What is pendulum experiment?
The Pendulum Experiment is an experiment about gravity. Pendulums (or pendula if we are being exact!) are a fascinating scientific phenomenon.
What forces are acting on a swing?
When the swing moves from the lowest point up to either peak, the main force acting is momentum; and when the swing falls from either peak to its lowest point, the main force acting is gravity. If you do not pump your legs fast enough, air resistance along with gravity will keep you down.
How do pendulums work physics?
A pendulum consists of a mass (known as a bob) attached by a string to a pivot point. As the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion. The force of gravity acts in a downward direction and does work upon the pendulum bob.
What is a pendulum and what causes it to swing?
A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position.
What affects the swing rate of a pendulum?
The swing rate, or frequency, of the pendulum is determined by its length. The longer the pendulum, whether it is a string, metal rod or wire, the slower the pendulum swings. Conversely the shorter the pendulum the faster the swing rate.
Why doesn’t mass affect a pendulum?
The reason the simple pendulum has no dependence on mass is because the mass gets to “count” for two different things. (The same thing happens in freefall motion, where all things of all weights fall at the same rate.) Mass counts for inertia, or the “m” in “F=ma”.
Does mass affect a pendulum?
(Mass does not affect the pendulum’s swing. The longer the length of string, the farther the pendulum falls; and therefore, the longer the period, or back and forth swing of the pendulum. The greater the amplitude, or angle, the farther the pendulum falls; and therefore, the longer the period.)
Does pendulum period depend on mass?
The period of a pendulum does not depend on the mass of the ball, but only on the length of the string. Two pendula with different masses but the same length will have the same period. Two pendula with different lengths will different periods; the pendulum with the longer string will have the longer period.
What should you not ask a pendulum?
You should NEVER ask your pendulum about someone without their permission. Whether that’s feelings, cleansing a space for them, anything. Only if they have given you permission. If you ask something like the example above, it’s unethical.
What does yes look like on a pendulum?
Here’s an example of how to program the “yes” signal: Holding the pendulum in position, say “When I ask a question and the answer is yes, move like this, in a clockwise circle.” (or whatever signal you’ve chose for “yes”).
What is a dowsing chart?
Dowsing charts can be used for any dowsing application. Most often, they are used in health and personal growth dowsing, or when dowsing for energies. But you can use them in any type of dowsing where there are multiple possible answers, or if you have an interest in the intensity or effectiveness of something.
