Instructions are in the simulation (I Symbol) This project should help students who are studying this at school. I made this project because i recently learnt it at school, and it can be confusing for some people. drag the box to a position above the pivot, then press space to drop it. Press the green flag to reset after dropping the box. To change the box' weight, click on the +/- buttons.
Feel free to comment and use it in your games. This is realistic! This took about a day to make. Update;v1.01: You can now adjust the weight of the box.
