[https://forum.defold.com/t/apply-impulse-in-2d-physics/74388](https://forum.defold.com/t/apply-impulse-in-2d-physics/74388) [https://github.com/defold/defold/issues/8256](https://github.com/defold/defold/issues/8256) [https://github.com/defold/defold/pull/8712](https://github.com/defold/defold/pull/8712) [https://github.com/orgs/defold/projects/42/views/1](https://github.com/orgs/defold/projects/42/views/1) I was completely unaware of this before. I previously used `apply_force` to achieve functionality similar to `apply_torque`, and set `linear_velocity` to achieve functionality similar to `apply_linear_impluse`. I suspect this is due to a lack of relevant information in the Defold Manuals and Defold Examples. Therefore, **I plan to write related documentations and examples for the Defold Manuals and Defold Examples in my spare time.** [https://defold.com/manuals/](https://defold.com/manuals/) [https://defold.com/examples/](https://defold.com/examples/) ---

In fact, when I searched “Defold apply\_impluse” on Google, I couldn’t directly find the documentation for b2b.body. ---

I plan to add apply\_torque example and apply\_linear\_impluse example on Defold Examples ---

I made a apply\_torque example. After the pull request above is approved, I will submit another pull request for this example, because I don’t yet know how to submit two pull requests simultaneously. > **[GitHub - JuLongZhiLu/defold-apply\_torque-example](https://github.com/JuLongZhiLu/defold-apply_torque-example)** > > Contribute to JuLongZhiLu/defold-apply\_torque-example development by creating an account on GitHub. ---
