Lever Physics

In this game there will be a lever and some items, you need to drag the items to the lever and make it balanced. On the lever there are markings indicating the distances between the position of the marking and the pivot of the lever, below the items there are also labels of their weights.

You need to put the items on the lever such that the moments on both sides are the same. For example if there is a 200g item hanging on the 3m mark on the left, then the moment on the left is 200 x 3; and if on the right side there is a 300g item hanging on the 1m mark and a 100g item hanging on the 3m mark, then the moment on the right side is 300 x 1 + 100 x 3 and so the moments on the two sides are the same and two sides are balanced.

The faster you can finish a level, the bigger your score is going to be. There are a total of 10 levels and the levels will be harder and harder.
