Hooke's Law

What is the limit of proportionality?

At a certain point, the graph bends and the line slopes up more steeply. This point is called the limit of proportionality,

What does F stand for in F=kx?

F: is the force in newton's, N

What is Hooke's law?

a law stating that the strain in a solid is proportional to the applied stress within the elastic limit of that solid.

what is the spring constant?

is the measure of the stiffness of the spring or material.

What will happen if a spring is stretched too much?

it does not returns to its original length when the load is removed. It becomes deformed.

What is the extension?

it is the increased length when an elastic object. such as a spring, is stretched. The extension of an elastic object is directly proportional to the force applied to it

What does k stand for in F=kx?

k: is the 'spring constant' in newton's per metre, N/m

Rearrange the formula F=kx to find the spring constant

k=F/x

What is the elastic limit?

the maximum extent to which a solid may be stretched without permanent alteration of size or shape.

What does x stand for in F=kx?

x: is the extension in metres, m

Rearrange the formula F=kx to find the extension

x=F/K
