Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.

### Instruction:
Describe the concept of 'inverse dynamics'.

### Input:
No input

### Response:
Inverse dynamics is a branch of mechanics that focusses on predicting the forces and torques in a system. It is the process of determining the forces or torques present in given conditions from a desired motion and the environment's properties. Inverse dynamics can also be used to calculate the unknowns in a given system and uncover the underlying laws of motion. By understanding the interplay of various forces, it provides powerful insight into the control of robots and other dynamic systems.
