The string in a yo-yo is wound around an axle of radius 0512 cm the yo-yo has both rotational and translational motion, like a rolling object, and has mass 0206 kg and outer radius 188 cm starting from rest, it rotates and falls a distance of 120 m (the length of the string) assume for . The physics of a yoyo | torque = r x f #3 410 views shubham gupta, associate software engineer at tech mahindra (2016-present) what is the physics behind the yo-yo. A yo-yo of mass m has an axle of radius b and a spool of radius r its moment of inertia can be taken to be mr^2/2 and the thickness of the string can be neglected. The wizardry of the yo-yo is a sight to behold as the laws of physics get stretched to their limits the yo-yo school in northampton, ma, is fun and educational, as attaining jaw-dropping skills in the craft runs parallel with deconstructing the principals of physics. The yo-yo oscillator (analysis of a nonlinear system using spice) randall d peters department of physics 1400 coleman ave mercer university macon, georgia 31207.
The physics as it falls, the yo-yo loses gravitational potential energy and gains both translational kinetic and rotational kinetic energy at the end of the fall the . In everything that we do, there is some aspect of physics involved in it even if we are just standing still on the ground, or leaning up against a wall, there are still numerous forces acting upon us this paper will tell of the physics involved in throwing a yo-yo when you release a yo-yo . The physics of a yo-yo in everything that we do, there is some aspect of physics involved in it even if we are just standing still on the ground, or leaning up against a wall, there are still numerous forces acting upon us.
So, this says that the angle needed to pull the yo-yo so it doesn’t slip only depends on the ratio of the inner and outer radius note that r would be smaller than r so that the ratio would be . Unlike most editing & proofreading services, we edit for everything: grammar, spelling, punctuation, idea flow, sentence structure, & more get started now. Hello pantera2, tar_heel_v's comment notes one good explanation of yo-yo physics here are two more: how do yo-yos work why do they come back up after being thrown down.
Such a yo-yo, with the two bigger discs having radius r = 400 cm and mass m = 300 g each and the smaller disc in the middle having radius r = 0700 cm and mass m = 500 g the string is taken to be massless, and infinitely . Message: yo-yo's simple are very cool, analyzing their behavior in anything but the simplest set-up is very difficult basically, a yo-yo transfers potential energy into kinetic energy as it falls (or really is thrown) down the string. Yo-yo (yō′yō′) n pl yo-yos 1 a toy consisting of a flattened spool wound with string that is spun down from and reeled up to the hand by motions of the wrist 2 . Mechanical study of a modern yo-yo the elementary physics of the yo-yo with a very good and clear description of the device allowing the free rolling, . A cross between juggling and yo-yoing, astrojax consists of 3 weighted balls on a string that you swing, rebound and rotate rhythmically there are tons of tricks you can try, or you can invent your own whizzing, spinning, and flipping combinations.
The yo-yo might seem like magic, but it is just physics at work there are three parts to the basic yo-yo: the two disks and the axle that joins them. A yo-yo (also spelled yoyo) is a toy which in its simplest form is an object consisting of an axle connected to two disks, and a length of string looped around the axle, similar to a slender spool working:. To a physicist, however, a yo-yo is a remarkably fun example of a flywheel, said gordon jones, assistant professor of physics at hamilton college your source for the latest research news follow . Dept of physics, univ of toronto frame where the yo-yo is moving with speed v and in a frame moving to the right with speed v where the yo-yo is only rotating .
Yo-yos can do some incredible tricks, and, generally, the science is pretty straightforward - the two hemispheres of a yo-yo are attached to an axle that moves up and down a piece of string but what happens when you take the string away as yo-yo champion ben conde shows in the latest episode of . My students need 24 duncan yo-yos, 1 book of yo-yo tricks, and 11 different non-fiction books about energy, force, gravity and motion my students need to build their background knowledge about energy, gravity, force, and motion by reading the different non-fiction books listed under resources. In order for a yo-yo to go all the way down and up, enough energy must be stored in angular momentum to overcome the potential energy of lifting a yo-yo’s mass the distance of the length of string into the air. Educational physics toys that demonstrate the principles of physics physics toys allow one to see first hand the different principles of physics in action they are an easy and inexpensive way to visualize certain concepts which would otherwise be difficult to grasp.
