## About this tutorial


    ProCalc 1.6 introduces kinetic calculations, enabling – among other things – joint forces, moments, and powers to be calculated. This tutorial describes in detail how the new functions work by presenting a suggested workflow for implementing kinetic calculations for a lower body kinematic model.


> ⚠️ **Note**  
> ⚠️ This tutorial covers how to calculate kinetics from a marker-based system. ProCalc does support kinetics from a Theia system, but that is not covered in this guide.

About the data for this tutorial

To follow this tutorial, navigate to *C:\Program Files\Vicon\ProCalc\Help* and unzip the *ProCalc Tutorials Data* file. Choose a path or directory that has sufficient read/write permissions and that you can remember and access easily (eg, *C:\Users\Public\Documents\Vicon*). If you have completed a ProCalc tutorial in the past, you may have already completed this step.

For this tutorial, we will use the *Kinetics* session. Within this folder, there is one trial (*Walking01.c3d*). This trial uses the Plug-In Gait marker set, and the Plug-In Gait model was applied to calculate segment orientations that are used in this tutorial.

To access the trials in ProCalc, ensure you have a hierarchy that looks like the example below, though the specific path will depend on the location of your extracted data.

> ✅ **Tip**   
> ✅ If you want to save any of the variables calculated in this tutorial to the C3D, remember to select **Save to C3D** for each variable.
