you can find the center of gravity of a meter stick by resting it horizontally on your two index fingers, and then slowly drawing your fingers together. first the meter stick will slip on one finger, and then on the other, but eventually the fingers meet at the cg. why does this work?

Respuesta :

If the fingers' distances from the centre of gravity (CG) differ, the fingers closer to the CG will support a greater portion of the meter stick's weight, resulting in zero net torque on the stick.

Because of the greater vertical force, there will be more friction between the stick and the closer finger, making it simpler to pull the finger farther from the centre of gravity.

The finger that is farthest away will glide more readily and come closer to the CG as a result. That finger will have greater friction and stick when it is the one that is closest to the CG. After then, the other finger will glide. The procedure is then repeated. The finger that is further from the Cg will move toward it, and finally the two fingers will meet at the CG.
