# Hookes law set up

Today is all about stretching students' knowledge of hooke's law by exploring the relationships between forces, mass, and displacement plan your 60 minutes lesson in science or springs (physics) with helpful tips from sara leins. Feynman has a great thing where he talks about the reason a rubber band is stretchy: there are actually long strands, and the thermal, random, vibrating motion of it bumps into these long strands and makes them crumpled up that's the natural state of it, and when you remove it from that state (by stretching the strands),. To investigate hooke's law and to determine the spring constant for two springs and a rubber band time allocation: 1–2 on a force versus elongation graph, the elastic limit will show up as the point where the slope of the line changes or before beginning, set up data tables similar to data tables 1 and 2 data table 1. Also, because it is a close approximation of all solid bodies (as long as the forces of deformation are small enough), numerous branches of science and engineering as also indebted to hooke for coming up with this law these include the disciplines of seismology, molecular mechanics and acoustics. For more information: [email protected] http:/ /www7activemedicalcom/ [email protected] After watching this video, you will be able to explain what hooke's law is and use the equation for hooke's law to solve problems a short quiz this is because the materials contain long chain molecules that are wrapped up in a bundle and can straighten out when stretched those are the materials we choose for. How can mathematical modelling determine the critical length of rope required for an exciting yet safe bungee jump bungee jumping kevin lord further maths support programme the modelling cycle the problem set up a mathematical model analyse the problem interpret / validate the solution. Springs set of 5 - hooke's law for verification of hooke's law this is a set of 5 springs with different spring constants pre-stress has been removed to give accurate results the springs stretch 2 cm with a load of 05n, 1n, 2n, 3n and 5n respectively springs come with a built in ring to hang, with a hook to carry weights.

Independent variable- force in newtons the weights are putting upon the spring dependent variable- the length of the spring experimental design: materials- ○ hooke's law apparatus ○ weight set ○ ruler/meter stick procedure- 1 set up apparatus determine the length of the spring in an unstretched. This is an example of a common experiment used to investigate hooke's law method set up the apparatus as in the diagram add a 10 g mass to the holder and record the spring length this follows hooke's law which states that the extension of an elastic object (like a spring) is directly proportional to the force added. Hooke's law and a few simple lessons from physics statement of hooke's law the physical setup in which a mass is connected to a spring is a rather ubiquitous one for example molecular structures are often so modelled we don't consider gravity in this situation, so there are only two constants of relevance to us.

Hooke's law it is well known that the displacement of a spring is proportional to the force acting upon it, that is, f = kx the proportionality constant k is called hooke's spring constant consider a laboratory experiment a slope and a y- intercept in this case, we set up the following linear system ax = b, or more precisely. In mechanics and physics, hooke's law of elasticity is an approximation that states that the extension of a spring is in direct proportion with the load applied to it many materials obey this law as long as the load does not exceed the material's elastic limit materials for which hooke's law is a useful approximation are known. Hooke's law says that the opposing force of a spring is directly proportional to the amount by which the spring is stretched how accurately hooke's law describe the behavior of real springs can springs be used to make accurate scales for weighing objects spring into action and find out for yourself with this project.

Hooke's law is an empirical physical law describing the linear relationship between the restorative force exerted by a spring and the distance by which the spring is displaced from its equilibrium length a spring which obeys hooke's law is said to be hookean in addition to springs, hooke's law is often a good model for. A secondary school revision resource for aqa additional gcse science about forces, elasticity and thier effects. Define hooke's law hooke's law synonyms, hooke's law pronunciation, hooke's law translation, english dictionary definition of hooke's law n the principle that the stress imposed on a solid is directly proportional to the strain produced, within the elastic limit a law in physics stating that.

## Hookes law set up

The set-up was prepared by hanging the spring vertically downward with an attached mass m 2 hooke's law is valid only for small displacements3) this equation is commonly known as hooke's law where k is the spring constant 1 k= −mg y (1 1 for experimental processes on measuring the spring's elongation we.

• State whether or not the rubber band obeys hooke's law, and justify your answer with reference to your data remember, the answer will likely be more complicated than a simple yes or no this account should be very short—it may not take up more than a handwritten page so, include only substantive information that.
• Hooke's law is a principle of physics that states that the force (f) needed to extend or compress a spring by some distance x scales linearly with respect to that distance that is: f = kx, where k is a constant factor characteristic of the spring: its stiffness, and x is small compared to the total possible deformation of the spring.

Hooke's law data table setup the data that you will need to record are the rest position of the spring (same for each trial), stretched position of the spring, and the total mass hanging from the spring to set up a data table (a sample is shown at right): open the graphical analysis program label the first. By acting like springs of course he means hooke's law here is a plot of force vs stretch for the same spring i used in the first set up after moving it back and forth a couple of times if just look at the points where the rubber band force stops decreasing, would this plot look like a hooke's law plot. Solution: hooke's law example problem 1 setup the k of the spring is 20 n/m δx is 25 cm we need this unit to match the unit in the spring constant, so convert the distance to meters δx = 25 cm = 025 m plug these values into the hooke's law formula since we're looking for the force required to pull the. However, we want displacement from the (new) equilibrium position, so we move the origin to s , which doesn't change the x ¨ term the spring behaves the same way as it would without the constant gravitational force (as long as the displacement stays in the region in which hooke's law holds, of course).
