Press the green flag to the left to begin the program. Slide to desired values. Click "Glide" to and watch the object glide. Feel free to use the custom block (you will have to create the variables m, v, u, Cx, and Cy I used) by dragging the define block into your backpack. The list and pen commands aren't necessary. If you do, please mention this project is where you got your curving objects from.
