What is the equation for calculating spring constant?
F = ke, where F is force applied in Newtons, k is the spring constant in N/m, and e is extension in meters
How can you find the spring constant from a force-extension graph?
The spring constant is equal to the gradient of the straight line section of the force-extension graph
What is the limit of proportionality in a force-extension graph?
The limit of proportionality is the point on the graph beyond which the extension of an elastic object is no longer directly proportional to the force applied
