Title: Lever Physics

Viewed: 4,377 views
Description: In this game, your goal is to balance the lever by putting all of the given objects onto it. You need to click and drag the objects onto the lever until the moments on both sides of the lever are the same, for example, if a 200g item is hanging under the 3m label on the left side, then the moment on the left is 200 x 3; and if on the right side a 300g item is hanging under the 1m label and a 100g item is hanging under the 3m label, then the moment on the right side is 300 x 1 + 100 x 3. In this case, the moments on the two sides are the same and therefore the lever will be balanced. If you have placed an item to an incorrect position, you can click and drag it back to the bottom of the screen.

Educator's Review: This is a game where players can practice balancing weights by understanding the physics behind it. At the start of each level, you will be given a lever which has labels to indicate the distances between the marked positions and the pivot of the lever. The objects and their weights are displayed at the bottom of the screen. You need to click and drag the objects onto the lever until the moments on both sides of the lever are the same. Each level increases the challenge and the number of objects to be balanced.
Please Note: Players need to complete each level within a set amount of time, which will frustrate players who prefer to work more slowly. Additionally, each time you lose you have to restart from the first level rather than what you are currently up to.
