Potential energy stored in a spring (video) | Khan Academy
Learn about the force required to compress a spring, and the work done in the process, and how this relates to Hooke's Law, which defines the restorative force of a spring.
Spring potential energy and Hooke's law review - Khan Academy
Review the key concepts, equations, and skills for spring potential energy and Hooke's law. Understand how to analyze a spring force vs. displacement graph.
Vertical springs and energy conservation - Khan Academy
Now the spring force is less than the force of gravity and so gravity wins in that case and it keeps going back and forth. We're gonna ask ourselves the same question we did before.
Spring force and Hooke's law (article) | Khan Academy

Spring force and Hooke's law (practice) | Khan Academy
Check your understanding of spring force and Hooke's law in this set of free practice questions.
Spring forces (article) | Oscillations | Khan Academy
The force of a spring is calculated according to Hooke’s law, named for Robert Hooke, a British physicist who developed the formula in 1660. Hooke originally stated the law in Latin: "Ut …
Period of a mass on a spring (video) | Khan Academy
Learn what affects the period of a mass on a spring (mass and spring constant), and what doesn't affect the period of a mass on a spring (amplitude and gravitational acceleration). Created by …
What is elastic potential energy? (article) | Khan Academy
The energy is stored until the force is removed and the object springs back to its original shape, doing work in the process. The deformation could involve compressing, stretching or twisting …
