The spring constant, k, is different for different objects and materials. It is found by carrying out an experiment. For example, the unloaded length of a spring is measured.

Materials under stress The force-extension graph. ... Using the graph, calculate the work done to extend the spring from 0 m to 0.10 m. Show answer Hide answer. The area under the line is a triangle: ...

Now, I can plot spring force vs. stretch (oh, convert stretch to meters instead of centimeters). Here is the data table. Yes, you can make that plotly graph right in class.

Many types of mechanical systems use elastic potential energy. The most common device that uses this type of energy is a spring. Credit: Svjo. When a force is applied to a spring, it is placed in ...

But if you compress a golf ball too much, it doesn't return to its original state. Instead, it gets smashed up such that it is deformed. It still has spring-like properties, but it's just not the ...
