Mathematics foundation gcse prep exam checklist work done and power forces and elasticity investigating hooke's law moments levers and gears hydraulics students will not sit an official exam instead they will continue to work on coursework during the exam slot that media has been placed in. In the above plan excerpt, the student has talked about factors that may affect the length of the spring they have identified what they want to vary (the mass) and noted how to make it a fair test some science has been introduced (in this case hooke's law) and it has been used to help write a basic prediction top stuff. Spring constant = force ÷ extension ü 12 cm = 012 m ü 014 kg = 14 n ü 14 n ÷ 012 m = 116 n/m ü 1bii [3 marks] extension = force ÷ spring constant ü = 4 n ÷ 116 n/m ü = 034 m ü 2a [2 marks] a ü it has the steepest gradient ü 2b [2 marks] it has reached its limit of proportionality ü so no longer obeys hooke's law.
Newton's second law coursework newton's second law is a way of finding the force that is acting on a certain object by using the known mass of the object and the projected acceleration and that the mass is this student written piece of work is one of many that can be found in our gcse forces and motion section. Physics revision site winner of the iop web awards - 2010 - cyberphysics - a physics revision aide for students at ks3 (sats), ks4 (gcse) and ks5 (a and as level) help with gcse physics, aqa syllabus a as level and a2 level physics it is written and maintained by a fully qualified british physics teacher topics.

Forces & elasticity – hooke's law, spring constant, elastic potential energy forces can change the shape of objects hooke's law the extension of an elastic object (like a spring) is directly proportional to the force applied, provided the limit of proportionality is not exceeded force = spring constant x extension ( newtons, n.
A short revision video explaining how forces change the shape of objects, how we show this using graphs and make calculations using hooke's law gcse physics. Title: hooke's law aim: to determine the spring constant equipment: retort stand (with clamp) spring (with hook) masses ( 100g, 200g, 300g, 400g, 500g ) ruler variables: independent variable: changing the mass ჻ weight force (f) dependent variable: the extension of the spring δx control variable: “spring.
Practicals in this specification include investigating factors that determine the strength of an electromagnet and investigating the relationship between force and extension for a spring exam questions will be asked on the practicals, but there is no coursework or practical exam this qualification is available for teaching now.
