Why do long elastic bands stretch further than short elastic bands?

If there is more elastic there is more elastic to stretch this means the actual extension is longer.
For example if you take one piece of elastic and attach a weight to the end of it while it is fixed to something eg. a table and then drop it off the edge of the table you can measure the difference between the extended length and the non stretched elastic. You can repeat this as many times as you like to make sure you have the correct length. Repeat this with continually longer pieces of elastic and you should see a noticeable difference in the length of extension.
For this experiment you will need a mass, that will remain constant; Varying lengths of elastic, blu tac or another method to attach the elastic to a table, and some way of measuring the lengths of the elastic and its extension.
Throughout this experiment your dependent varible will be the length of the extended piece of elastic, Your independent varible will be the un-extended length of the elastic, and your control varible is the mass attached to the elastic. There are many risks with this experiment that may cause harm to the scientist conducting it.
For example throwing or dropping the mass at your toe can result can in a broken toe. This can be reduced by getting a responsible adult to carry the weight for you. In addition to this the elastic may well snap and hit you in the face. If it catches your eye this can blind you. To reduce the chance of this happening, wear goggles or other eye protection.
A context of this investigation would be: "How does the length of a bungee cord affect how far the bungee jumper will fall down."
This answer is very useful for anybody completing The physics ISA (4403) in June 2012.

∙ 14y agoyes they are stronger since they are bigger. Won't snap as easily.
Wiki User
∙ 14y agoYes because it's harder to break due to the thickness it has
Wiki User
∙ 14y agobecause they are longing so they stretch further

∙ 12y agothick is hard and fat thin is bendable and could stretch

What happens to information in short-term memory that is not further processed or rehearsed?
The information in short-term memory that is not further processed or rehearsed decays or fades away. Information is stored in short-term memory for approximately 20 to 30 seconds.
You had your spacers for about 36 hours and had them removed will your teeth shift back to their original spots you decided not to get braces?
Yes. Removing the spacers early and without placing the orthodontic bands will result in the teeth returning to their original positions in a very short time.
Is a leaf rake a screw?
There may be a screw holding the handle to the rake. However, it would be a stretch of the imagination to consider a rake as a screw.Perhaps the only similarity is that the rake may have a wedge-shaped fan at the bottom. And, screws function like wedges. But, here the analogy would stop short.
What is a locaust?
Locust is the swarming phase of short-horned grasshoppers of the family Acrididae. These are species that can breed rapidly under suitable conditions and subsequently become gregarious and migratory. They form bands as nymphs and swarms as adults-both of which can travel great distances, rapidly stripping fields and greatly damaging crops.

Does the amount of stretch affect the distance a rubber band will travel what material do you need for that experiment?
Yes because you could stretch the rubber band long and it will go far but if you stretch short it will not go as far. the materials you need is rubber bands a tape measure or meter stick paper pencil
Is a firm's demand for labor curve is more elastic in the short run than in the long run?

Which of the following is a good example of a good with elastic supply in the short run?
Passenger Airplanes
Is supply more elastic in the short run than in the long run?
Most of them are more elastic in the long run,because all factors of production are variable,not fixed.
