Answer 3

The pendulum is a body suspended from a fixed point so as to swing freely back and forth under the action of gravity. Its regular motion has served as the basis for measurement, as recognized by Galileo. Huygens applied the principle to clock mechanisms. Other applications include seismic instrumentation and the use by NASA to measure the physical properties of space flight payloads. The underlying equation is at the heart of many problems in structural dynamics. Structural dynamics deals with the prediction of a structure’s vibratory motions. Examples include the smoothness or bounciness of the car you ride in, the wing motion that you can see if you look out of the window of an airplane in a bumpy flight, the breaking up of roads and buildings in an earthquake, and anything else that crashes, bounces or vibrates. With this pendulum motion as a point of departure, complex structures can be analyzed.


The pendulum serves as an illustration of Newton’s Second Law, which states that for every force there is an equal and opposite reaction. The simpler experiments illustrate another of Newton’s laws, namely, that a body in motion continues in motion unless acted upon by another force. The pendulum offers an extensive array of experiments that can be done using easy to obtain, inexpensive materials. The measurements require no special skills and equipment. The graphical results of each experiment are given, and can be compared to the results calculated from a simple equation if desired.

smart enough for ya?

Answer 5

As the pendulum swings, it goes from a high position (maximum extent of swing) to the lowest position (midpoint of swing). This change in height is caused by gravitational acceleration from the earth's attraction. That acceleration is a constant. If the pendulum shaft is longer, the arc distance to swing from highest point to lowest will be greater. Thus, it will take longer to fall to the lowest or midpoint of the swing. It does not matter about the amount of swing (slight, or wider), but the radius of the arc, which governs the amount of time it takes to go from the highest part of swing to lowest part of swing.
For example, for a constant length shaft, suppose the swing is only two inches from extreme to midpoint. The pendulum accelerates under gravity, but has little speed when it reaches the midpoint, as the angle between gravity and the swing shaft is so slight. Thus, the sideways effect of the gravitational attraction is low, and the pendulum is accelerated by gravity very slowly. Its final speed at the bottom or midpoint of swing is low, so it took quite a long time to get there.
If the amount of swing for the same length shaft is more extreme, the angle between the shaft and the gravitational attraction is greater. There is more effect of gravity upon the pendulum bob at the end of the shaft, the acceleration is greater, and the speed of the pendulum at the bottom of the swing is higher. But the time it took to cover the greater angle of swing is the same as the time it took to cover the lesser angle of swing.
That shows that the pendulum time of swing is independent of the breadth of angle of the swing. Only making a change in time of swing is by changing the length of the shaft (the radius of the swing, and thus the ratio of the length of that arc with respect to the angle of the swing).

Answer 6

i used ur means of smart and copy pasted the interweb *nerd-snort*

Answer 7

haha ok so it didnt help?

Answer 8

u think im gonna read all that PHAHAHA LOL

Answer 9

lol fine ill try again

Answer 10

paraphrase it for me, child..i need an answer, not a bucket of em :P

Answer 11

lol okey dokey

Answer 12

The pendulum just affected by its length and gravity, not its weight!

Answer 13

yes i know that but i just need the logic to why that happens

Answer 14

I mean the period of pendulum*

Answer 15

Who read it, my vision already so poor :(

Answer 16

wait what? i just need WHY its the length

Answer 17

and not the weight

Answer 18

It's length's likely the radius, so of course it decide the period!

Answer 19

the shorter the radius tha faster it swings?

Answer 20

Weight actually is canceled out by the gravity ( my guess)

Answer 21

umm...okay thanks so much, ill figure this out! :)

Answer 22

Since the pendulum is vertical movement so it's affected by gravity!

Answer 23

Wow, what's a day to please everybody around me ;)
