Tutoring physics, you might encounter the concepts of stress and strain. The tutor defines them.<\/h1>\n

In physics, stress and strain are related, but have very different meanings. A helpful idea is that stress is imposed on an object, while strain measures its reaction.<\/p>\n

stress<\/strong> noun<\/em>:
\nthe force per unit area applied to an object. In this context, the object is likely not mobile; therefore, the stress likely has the effect of changing its shape, possibly not permanently.
\n<\/br>\n<\/div>\n

\n

strain<\/strong> noun<\/em>:
\nthe change in length the object experiences (resulting from the stress), divided by its original length. An object compressed from 100.cm to 90.cm experiences a strain of -10.\/100., or -0.10 (aka -10.%).
