Gravity makes a pendulum swing back and forth. The object starts at one point, and then moves in a circular motion to the apex of it's next point. The kinetic energy becomes less and less as time goes on if no extra energy is added.

vertical. this force always acts towards the centre and therefore it sways back and forth.

What could we use instead if these computers was not available?
Fingers and toes, an abacus, a slide rule, numerical charts, the phone, mail for sending videotapes back and forth.
Describe how the front buffer and back buffer work together in double buffering?
The front buffer is the image that is currently being displayed on the screen. The back buffer is the image that is being drawn to by a program. These switch back and forth, (moreover the information is transferred from the back to the front buffer), which lets the program draw exclusively to back buffer, where it will not be slowed down by the screen's refresh rate, as it would be if every element were drawn directly to the screen.
Is receiprocating pump advantageous or centrifugal pupm?
A reciprocating pump is an advantageous pump. Centrifugal pumps convert energy into rotation to power themselves. A reciprocating pump uses a back and forth linear motion.
What does a toggle switch do?
Toggle = back and forth, or on and off. A toggle switch toggles (turns) a light or other device on or off. Good example is a light switch (the wall kind)-- a toggle switch must also be of the "throw the stick back and forth" kind. Which a light switch basically is.
Why does your speakers vibrate when it is to loud?
Because you have them too loud. It will ruin your speakers if you keep it up. Actually, they always vibrate - it is the conversion of electrical signals to sound waves that causes the cone of a speaker to move back and forth rapidly, creating the sound wave that we hear. If the vibrate is more of a 'buzz', then the speakers are being pushed beyond their capacity, and will fail, as the original poster noted. Sound IS vibration. The sound waves hit your ear, and they cause your ear muscles to vibrate back and forth, and small organs convert this physical movement back into electrical energy which your brain then recognizes as sound. Sound can not travel in a vaccuum, it needs air or another medium to travel through.
What swing back and forth and measures time?
A pendulum

How is swinging on a playground swing related to resonance?
it all has to do with a pendulum when you swing back and forth you are using potenial and kinetic enery
What are examples of things that move back n forth?
Pendulum, yoyo, Newtons Cradle, swing...
A pendulum that takes 5 seconds to make one single swing back and forth has a period of?
5 seconds
Does the distance a pendulum travels decrease with each arc?
if by arc you mean the "Period" of the pendulum then yes, it does: with each revolution the period of the pendulum (the time taken to swing back and forth once) does decrease.
What is the number of back and forth swings a pendulum makes is called?
If you mean the time it takes to swing from start to finish (top to top) this is called the period and if it is the number of swings per second this is know as the frequency.
Why does a pendulum swing back and forth instead of just swinging down and stopping?
because it has to keep moving until it can't move no more
What is a clocks pendulum?
The pendulum of a clock is the long weighted bar that swings back and forth in the case below the clock. It was discovered several hundred years ago that the time it takes for one swing of a particular pendulum is constant, no matter how big or small the swing is. It can, therefore, be used to measure time.

Why do people add pennies to big ben?
by adding pennies , it changes the time taken for the oscillations of a pendulum ( for it to swing back and forth ) . This can be adjusted by adding more pennies to the top, which makes the length of the pendulum shorter and thus swinging faster. However , if you want the pendulum to go at a slower rate , then you would add pennies to the bottom.
How can you make a pendulum swing without stopping Is it possible?
Every time the pendulum swings back and forth, some energy is lost to friction. Friction with air, and friction in the supporting string or whatever. If you manage to reduce this friction (for example, reduce air friction by making the pendulum swing in a vacuum), it will swing longer. However, you won't be able to reduce energy losses completely; it may swing longer, but not forever.
