Frequently asked questions
What is Topic 15: Forces and matter?
Elasticity, atmospheric pressure, liquid pressure and upthrust. 4 lessons in 1 subtopic.
What does a force-extension graph show?
A force-extension graph is a straight line through the origin while Hooke's Law applies, showing a linear relationship, and its gradient is the spring constant. The Elasticity Explained: Forces, Deformation and Springs notes cover this in full.
How do you calculate the spring constant?
Find the extension, convert it to metres, then use k = F ÷ e. The Spring Constant and Calculations notes cover this in full.
What is elastic potential energy?
Elastic potential energy is the energy stored in a stretched or compressed elastic object, like a spring, measured in joules (J). The Elastic Potential Energy notes cover this in full.
What is the elastic limit?
The elastic limit is the maximum force that can be applied to a spring before it becomes permanently deformed and will not return to its original length. The Spring Constant and Calculations notes cover this in full.
What is the spring constant formula?
The spring constant formula comes from Hooke's law, F = ke, rearranged to k = F ÷ e, where F is force in newtons and e is extension in metres. The Spring Constant and Calculations notes cover this in full.
What is the difference between elastic and inelastic deformation?
In elastic deformation the object returns to its original shape when the forces are removed, and energy is stored. The Elasticity Explained: Forces, Deformation and Springs notes cover this in full.
What does the gradient of a force-extension graph show?
The gradient of the straight-line section of a force-extension graph equals the spring constant. The Spring Constant and Calculations notes cover this in full.
How much energy is stored in a stretched spring?
The energy stored in a stretched spring is found with Ee = ½ke². The Elastic Potential Energy notes cover this in full.
