Incline Lab

My another essential is Physics which after math. This year we study with a new teacher and we have covered many lessons already.  We have a learn a lot new course and now we mostly focus on the incline. We have done a lab that connects to incline where we try to find the angle that the object starts sliding. The object is paper clip box and the surface is sandpaper. For the surface, we use sandpaper from the smoothes to the roughest.
