And if it does, you’ll be a Jenga legend. This will decrease the normal force between them, as well as the frictional force.īold move? Sure. What are the rules of Jenga The basic rules of Jenga are that players take turns removing a block from the tower, using one hand at a time, and stacking them on top without knocking the tower over. If you push the middle block ever so slightly up, you can move the upper stack up a little bit. The second trick is considerably more difficult, but it’s worth a shot. Couple it with the larger mass of the upper block, and there’s a decent chance it doesn’t move fast enough to topple over. If you make this push last only a fraction of a second, then the frictional force on the upper block doesn’t have enough time to get it moving. The million-dollar question, then, is how do you pull off the impossible move? You have two tricks at your disposal. If you aren’t careful, it will accelerate right off the top of the stack and tumble. Its a tower of smooth, rectangular wooden blocks with each level arranged at right angles to the one before it. Players take turns to remove a block from a tower and balance it on top, creating a taller and increasingly unstable structure as the game progresses. Jenga's success rests on its solid play value. Built on the simple premise of stacking blocks, Jenga engages players of all ages, across all cultures. That means there’s a horizontal force on the top block, and this force causes the block to accelerate. The beauty of Jenga is its simplicity and elegance. Jenga is a game of physical and mental skill. For every force, there’s an equal and opposite force. Yes, forces are an interaction between two things.

You have to push that much harder to accelerate the block. There’s also a frictional force between the top and middle block. With a greater normal force, there’s a much greater frictional force. This means that the bottom surface has to push up with an even greater magnitude. So what makes this middle block so difficult? Well, since there’s a block on top (or many blocks), there’s an extra downward pushing force. Finally, there’s the backwards-pushing frictional force. This is called a “normal” force, since normal means perpendicular. Both the stack above and below the middle block push on it in a direction perpendicular to the surface. Next, there are the two interactions with the surfaces. The gravitational force (the weight) is the downward pulling force due to an interaction with the Earth.
