*** WHAT'S COVERED ***
1. Force, Extension, and the Spring Constant
* The relationship defined by the equation F = ke (Hooke's Law).
* How the spring constant (k) is a measure of an object's stiffness.
2. Elastic Potential Energy
* The energy stored in a stretched or compressed object.
* The equation for calculating elastic potential energy: Ee = ½ke².
* How energy is transferred to and from an object's elastic potential energy store.
3. Worked Examples
* A step-by-step calculation to find the spring constant of a spring.
* A step-by-step calculation to find the elastic potential energy stored in a spring.
4. Interpreting Force-Extension Graphs
* How the gradient of the linear section represents the spring constant.
* How the area under the curve represents the elastic potential energy.
* The definition of the elastic limit, also known as the limit of proportionality.
