Hooke's Law

Front

Hooke's Law describes the behaviour of which kind of material under tension?

Back

elastic

Front

If F is force, k is spring constant and e is extension, Hooke's Law tells us that:

Back

F=ke

Front

When does Hooke's Law fail for a material?

Back

limit of proportionality

Front

In which side of the graph does the spring obey Hooke's law?

Back

To the left of point A

Front

Which statement most accurately represents Hooke's Law?

Back

The stretch of a spring is directly proportional to the force applied up to the limit of proportionality

Front

What word describes the additional length a spring gains when a force is applied?

Back

Extension

Front

An elastic material can change shape when ________ is exerted on it.

Back

a force

Front

A deformation is a change in _________.

Back

shape

Front

For this spring, Hooke's Law holds. What would you expect to happen to the extension if the force was doubled?

Back

The extension would double

Front

Calculate the spring constant.

Back

k = 10N/m
