# How does the Surface Free Energy Measurement Work?

1. The process for measuring surface free energy is also similar to the contact angle measurement.
2. For surface free energy measurement, there are 3 most widely used methods. They include the Neumann method, Fowkes method, and the Oss and Good method.
3. The selection of the method depends on the type of surface you are using in the experiment. It is recommended to study the literature related to the surface under consideration before you select the measurement method. For our demo, we will be using the Neumann method.
