Factors affecting stretching springs and rubber bands

factors affecting stretching springs and rubber bands If we take the example of stretching a rubber band when we use force to stretch an elastic object, such as an elastic band we are filling it with potential energy when we let go of the rubber band and it springs back to its original shape, the energy released is kinetic energy did you know kangaroos.

In today's post, i will be focusing on another type of potential energy – elastic potential energy click to learn more an accurate answer to this question “ elastic potential energy can be found commonly in stretched or compressed springs and stretched rubber bands” the key words are “stretched” and. Objects that this would apply to include things like rubber bands, sponges, and bungee cords, among many others in order to find the formula for elastic potential energy of a spring we need to look at hooke's law, which states that the force needed to stretch a spring is proportional to the displacement of the spring. The rubber band will oscillate and stretch when a force is applied to it which of the following the rubber band does obey hooke's law because you can determine a spring constant hang the divide the force by the elongation to get the spring constant of the rubber band which is a factor in hooke's law c the rubber. The flimsy-looking rubber bands don't have the same operational value as some of the other household stationary like duct tape the following year, thomas hancock patented rubber springs for various types of clothing ben noticed that rubber bands get hot when stretched and cool when released.

​if you pull too hard, the rubberband breaks partly due to the particles being stressed too much if you let go of the rubberband before it snaps then the molecules loosen again there are other factors involved, but that is the basics of what happens inside of a rubberband as said, scientists measure elasticity based on how. Apparatus and materials retort stand, boss and clamp mass hanger plus masses (100 g) metre rule selection of rubber bands, elastic cord marker pen health & safety and 3 how science works extension: students can investigate the effects of a range of factors, including width and thickness of the rubber band using a. Immediately think of a rubber band a rubber band yields a great deal to a distorting force, and yet it returns to its original length after the distorting force is removed can you think of some biological examples of elastic bodies in this chapter we will examine the elastic properties of materials 132 elasticity elasticity is a. Be built by connecting a mass to a rubber band if we con- sider only the longitudinal degree of freedom involving rub- ber extension, such an oscillator is characterized by greater damping than an equivalent oscillator with a harmonic spring this damping originates from the rubber band, and its modeling is a challenge for.

Of course, hooke's law only remains true when the material is elastic if a spring is permanently deformed (by something like crushing or overstretching), it will no longer return to its original position if you have ever played with a slinky and accidentally stretch it too far or bent it out of shape, you'll know that it doesn't perform. This lesson addresses the following questions: how do rocks deform, what factors play an important role in defining the behavior of rocks, what happens when rocks small metal springs rubber bands (cut in the middle to produce an elastic string) silly putty (enough to be shared evenly among the students in the time. A classic example of elastic deformation, and indeed, of highly elastic behavior, is a rubber band: it can be deformed to a length many times its original size, but upon release, it returns to its original shape heat causes atoms to vibrate, and in the case of metals, this means that the springs are stretching and compressing.

Sketch and describe the force and extension curve of an elastic material (eg elastic band or spring) when not stretched beyond its limit of proportionality sketch and describe the speed that a person can walk, run or cycle depends on many factors including age, terrain, fitness and distance travelled typical values may. Scientific knowledge: before doing the experiment i came to the conclusion that this experiment relates to hooke's law which states that extension is proportional to the load, meaning that if you stretch something with a steadily increasing force, then the length will increase steadily too by looking at various. Everybody knows that when you apply a force to a spring or a rubber band, it stretches a physicist would ask, how is the force that you apply related to the amount of stretch every physics experiment has a purpose, often phrased as a question that the experiment hopes to answer generally, we want to. Compressed springs and stretched rubber bands are examples of stored mechanical energy nuclear energy is energy stored in the nucleus of an atom— the energy that holds the nucleus together large amounts of energy can be released when the nuclei are combined or split apart gravitational energy is energy stored in.

Of a rubber band as a function of temperature and length, and use a maxwell relation to find the change in internal energy and entropy for an isothermal stretch this allows students to experimen- tally check the predictions of the entropic spring model for elastomers and observe that the entropy does indeed decrease as a. The deformation could involve compressing, stretching or twisting the object many objects are designed specifically to store elastic potential energy, for example: the coil spring of a wind-up clock an archer's stretched bow a bent diving board, just before a divers jump the twisted rubber band which powers a toy airplane. Proper answer is very elementary the definition of elastic in physics is unfortunately inverse of common sense elastic the more difficult it is to stretch, the more elastic a material is called to be because elasticity is defined by the ratio stress to strain and not vice versa 3 recommendations. This made the researchers wonder: were the three-dimensional structures they observed randomly occurring, or are there specific factors that control their the team was trying to make two-dimensional springs by taking two strips of rubber material of different lengths and stretching the shorter one to.

F = force applied to elastic material [n] k = spring constant [n/m] δl = change in length of the elastic material [m] methods this experiment investigated the stretching of rubber bands in an attempt to determine the conditions under which hooke's law applies their action the first step was to select three rubber bands of. Most of us are familiar with stretching and shooting rubber bands however, it is not immediately obvious to of the straight rubber bands against the inverse neo-hookean factor of stretch ratio consider the rubber band as a series of small masses connected with springs, as the rubber band is released every single. A mangonel uses the potential energy created by tension in an elastic band, or torsion in a twisted rope we'll be performing the calculations for the former, which is the more common approach in rubber band catapults potential energy of the rubber band hooke's law tells us that the force needed to stretch a spring (or in.

Various grades of 3m™ sandpaper using either spring scales or rubber bands in addition to number of factors: type of surface, amount of surface area contact, the force that presses the two surfaces together if spring scales are not available, use rubber bands along with metric rulers to measure the stretch of the rubber. Elastic bands do not obey hooke's law as the force applied is not proportional to the extension of the band typically, a fair amoutn of stress is required on stretching to produce a small amount of strainbut eventually, less stress is needed for the same amount of strain this is because the atoms/bonds.

A spring is an elastic object that stores mechanical energy springs are typically made of spring steel there are many spring designs in everyday use, the term often refers to coil springs when a conventional spring, without stiffness variability features, is compressed or stretched from its resting position, it exerts an. Rubber elasticity, a well-known example of hyperelasticity, describes the mechanical behavior of many polymers, especially those with cross-links contents [hide] 1 thermodynamics 2 models 21 freely-jointed chain model 22 worm-like chain model 3 integrated rubber network models 31 the molecular kink. F is the force in newtons, n k is the 'spring constant' in newtons per metre, n/m e is the extension in metres, m this equation works as long as the elastic limit (the limit of proportionality) is not exceeded if a spring is stretched too much, for example, it will not return to its original length when the load is removed.
