Aerobie aerospin yo-yo (color may vary) aerobie has paid great attention to the physics behind yo-yo technology and they've produced a product that reflects this knowledge read more published on january 28, 2009 laura nisbet 30 out of 5 stars one hyper yo-yo this yo-yo simply does not sleep adjust it according to the manufacturer's instructions all day long, but the yo-yo. Physics posted by anon sunday, november 24, 2013 at 11:22am torque, rotation and translation a yo-yo of mass m has an axle of radius b and a spool of radius r its moment of inertia about the center can be taken to be i=(1/2)mr2 and the thickness of the string can be neglected. Mechanical study of a modern yo-yo this article has been downloaded from iopscience please scroll down to see the full text article 2011 eur j phys 32 1097. When twirling a yo-yo (or any mass on the end of a string) in a circle, there is a centripetal force - the tension in the string our goal it to calculate it and compare it to the weight creating the centripetal force. Answerscom ® wikianswers ® categories science physics is a yo-yo a potential energy or a kinetic energy is a yo-yo a potential energy or a kinetic energy save cancel already exists would you like to merge this question into it.
This question has been around the net for a while, and i haven't seen a good explanation for it: a yo-yo is initially at rest on a horizontal surface a string is. Physics project on the yo-yo it's for bonus marks i need to calculate the angular momentum of a yo-yo when it leaves your hand the hand represents an inclined plane which imparts the spin i'm keeping it simple and won't involve friction what i'm trying to get at is the equation for acceleration. A yo-yo with an outer radius of r= 075 m and an inner radius ofr= 025 m lies on a frictionless horizontal table a string that is wound around the hub of the yo-yo spool is pulled horizontally with a force f= 15 n.
Physics term papers (paper 10757) on the physics of 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 term paper 10757. The demonstration capitalizes on the fact that the static friction force always opposes the tendency to slip a string is wrapped around the inner shaft of a large “yo-yo” like spool. Brown university physics department physics 0050/0070 acceleration of a falling yo-yo (l-15) theory: a yo-yo is made of two identical disks attached at their centers to a cylindrical axle, which has a smaller radius.
Yo-yo and note that when you suspend it, the string makes an angle of 22° with the vertical (a) what is the acceleration of the airplane (b) if the mass of the yo-yo is 400 g, what is the tension in the string x: y: title: physics 121c mechanics author: john g cramer created date : 9/23/2013 2:50:32 am. Active example 10-3 (find the yo-yo's speed) specify the properties of a yo-yo and observe the energy conversions as it unwinds its string and drops downward warm ups, puzzles, and “what is physics good for” applications from the just in time teachingmethod warm-upquestions are short-answer questions based on important. 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.
Gyroscopic stability keeps the yo-yo spinning in one direction and it's axis of rotation does not change the string is always perpendicular to the yo-yo's axis of rotation the yo-yo experiences two forms of momentum linear and angular linear momentum is momentum in a straight line and is present. How to use a yo yo a yo-yo is a classic toy that's seemingly simple but actually rather tricky to master it takes deftness and agility as well as careful hand coordination to successfully operate a yo-yo but with practice you can be a. Yo-yos are fun toys, but they actually involve quite a bit of interesting physics like angular momentum and gyro stability typically, yo-yos have strings attached to them, but professional yo-yoer, ben conde has some pretty impressive skills that llow him to use a stringless yo-yo stringless yo.
Yo-yo physics j0225 objectives/goals determine what effect (if any) the weight and string length of a yo-yo have on its sleep time, which is the time it stays at the bottom of the string when the yo-yo is thrown methods/materials one yo-yo, yo-yo strings, two dimes and two pennies the weight of the coins was determined using a scale.
A yo-yo is made of two identical disks attached at their centers to a cylindrical axle, which has a smaller radius a string is attached to and wrapped around this axle if the yo-yo is released, it displays both downward linear motion and circular motion about the axle to understand the motion of. By: nhi nguyen the physics behind a yo yo how a yo-yo works newtons first law parts of a yo-yo when on string tricks are performed, friction occurs due to the rubbing of the yo yo and the string friction acts between the string and the axle to resist further spinning motion, and potentially catch. I am a grade 11 student and i have a science project and i can't find the formulas to figure out the forces acting upon a yo-yo if anyone out there. 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 then students will explore and learn about physics concepts by using a yo-yo.
