Coursework marking criteria the 20-point scale methods of submission deadlines late submission extensions and exemptions extensions to assessed work nature all applications and evidence for extensions and exemptions are considered against the twin criteria of force majeure and evidence. Then you reach the point where they are all broken and you start to stretch the intermolecular bonds which are stronger than the cross-linking bonds on a force extension graph (as opposed to a stress-strain graph), you also have the effect of the band getting narrower, meaning it requires less force, for a while, to extend the. You should submit your claim as soon as you become aware of the problem and prior to the examination and/or coursework deadline an unanticipated and/or non-negotiable commitment to duties associated with an elected office, membership of a voluntary organisation, or service with reserve forces, as a result of. Describe the difference between a linear and non-linear relationship between force and extension calculate a spring constant in linear cases interpret data from an investigation of the relationship between force and extension calculate work done in stretching (or compressing) a spring (up to the limit of proportionality).
If circumstances prevent you from completing all required coursework before the end of the course, you should consider all options before deciding to request an extension in a course although extending a course is preferable to withdrawing, there are consequences associated with an extension.
Measure how a spring stretches as you apply an increasing force to it and you get: force/n 10 0 9 1 8 2 3 7 4 6 5 11 12 13 14 15 8 10 1214161820 extension/cm weight in newtons 1n 2n 3n 4n 5n 6n extension cm this shows that force is proportional to extension this is hooke's law it can be written as.
Science controlled assesment the extension of a rubber band depends on the force applied hypothesis i anticipate that an increase in the load on the elastic band will result in an increase in the extension of it i think that the extension will be proportional to the load on the elastic band i think that there will be a. Want to know how to measure the extension of a spring how do you plot the graph for your required practical all this and more in the latest gradegain required practical video about force and extension covers the basics of hooke's law as well.
Extenuating circumstances are defined as circumstances that could not reasonably be foreseen and that either (a) prevent a student from submitting work for assessment (whether by coursework or examination) or else (b) prevent the student from demonstrating / achieving their full potential in the assessment in question.
As an equation, hooke's law says that the force applied in newtons (or the restoring force -- it amounts to the same thing) is equal to the negative of the spring constant, k, of the material, multiplied by the extension, x, of the material, measured in meters we use the negative sign when we're talking about the restoring force. What the results mean the spring extended 5 mm each time a 10 g mass is added (which increased the force due to gravity by 01 n) this follows hooke's law which states that the extension of an elastic object (like a spring) is directly proportional to the force added.
