... out (parallel) so when demonstrated with a slinky spring, your hand movement would be moving forwards and backwards as shown below. An example of a longitudinal wave is a sound wave. So for example when we listen to music, the speakers ...

... applying enough force. When you stop applying the force, some materials retain their new shapes; these are plastic materials. Other materials return to their old shape when you stop applying the force; these are elastic materials. When you pull an elastic ...

... that the extension is proportional to that of the load, and so if load increases, so does the extension and so stretching the distance. He discovered that extension is proportional to the downward force acting on the springs and so ...

... elastic band go past its limit of elasticity. I also predict the more the weight the further the elastic band will go from its starting point. Apparatus: The equipment that I used for this experiment was: * Griffin 100g weights x4 * 1 metre ...

... the extension will be. 4. the material of the spring will affect the extension because different materials got different strength Prediction: I predict that the extension will be proportional to the stretching force so long as the string is not permanently stretched. ...

... to the spring, the further the spring will stretch. This is because extension is proportional to load and so if load increases so does extension and so stretching distance. Equipment: * 25swg Copper * 26swg Nichrome * 32swg Constantin * 32swg Nichrome * Stand * Clamp * Ruler * ...

... applied to the elastic band, the band automatically begins to repel that force that is stretching it, and when released the band moves back to its original position. When the band is stretched something is pulling the band in the ...

... a force stretches a steadily increasing number of springs, the length will decrease in a linear fashion. If the springs are stretched beyond the elastic limit, it will start behaving inelastically and will not return to its normal shape. It ...

... bonds, if the bonds break then the molecules cannot return to their original state. This is known as the elastic limit. Therefore, the number of molecules will effect the elastic limit of a material. The more molecules there are the ...

... that it will drastically affect the room temperature. Prediction I think that as the weights are added to the elastic band, the extension will not be proportional to the load. This is because I already know that this applies to springs (Hooke's ...

... to much with the heavier masses because the spring might become unhooked and weight would fall all over the place. Fair test I will keep this experiment fair by using the same spring each time to ensure the constant "k" stays the ...

... obeys hook's law. Prediction: When applying masses expands a spring it will go back to its normal shape in order to obey the hook's law. Apparatus *Clamp *Clamp Stand *Ruler *Hangar *Slotted Mass *Spring *Celotape. Safety: * Stand up while doing the experiment to avoid injuries when masses mistakely dropped. * Handle ...

... material becomes deformed. If the molecules are tightly bound to each other, even for a large amount of stress there will be little strain. If, however, the molecules are loosely bonded to each other, a relatively small amount of stress ...

... creating stress within the material, the molecular distances change and the material becomes deformed. Below the elastic limit, when the applied force is removed, the molecules return to their balanced position, and the elastic material goes back to its original ...

... The maximum amount of stress a material can withstand before becoming permanently deformed is called the elastic limit. I will keep the experiment a fair test by measuring the extension for each weight added, removing it and measuring the length of ...

... not return to its normal length once it has reached its elastic limit as it will be plastic, and I support my prediction with Hook's Law. To make this a fair test I will add and remove the same weight ...

... and I found out that ' Masses on spring oscillate in a way called Simple Harmonic Motions. The time for one of this oscillation is called time period. The time period depends on various things. By apply the laws of physics to ...

... proportional to the downward force acting on the band, and there will be a elastic limit where the band and the spring can't take no more and will constantly drop and with the band it will actually break. PILOT TEST: Before ...
