This time we'll call [`mj_forward`](https://mujoco.readthedocs.io/en/latest/APIreference.html#mj-forward), which invokes the entire pipeline up to the computation of accelerations i.e., it computes $\\dot x = f(x)$, where $x$ is the state. This function does more than we actually need, but unless we care about saving computation time, it's good practice to call `mj_forward` since then we know we are not missing anything.\n",
