Once you wind up the string of a yo-yo, any kind of yo-yo, and hold it in your hand, it has potential energy. In fact, it has not one, but two kinds of potential energy. It has potential energy because it can drop down, and it also has potential energy because it can unwind.

What are the physics of a yoyo?
Yo-yos display both linear momentum (moving up and down on the string) and angular momentum (spinning around). The angular momentum is what makes yo-yos the perfect tool for doing different tricks. A spinning object always tries to maintain its angular momentum, regardless of any forces trying to hold it back.
What is the moment of inertia of a yoyo?
Since a yo-yo is approximately a solid cylinder spinning about an axis through its center we can use the following formula to find its moment of inertia: I = 1 2 MR2 where M is the mass and R is the radius of the cylinder. The more mass away from the axis of rotation, the greater the yoyo’s moment of inertia.
What is the principle of Yoyo?
When you release a yo-yo, gravity acts on its center of mass to pull the yo-yo downward. Because the string of the yo-yo is wrapped around the yo-yo’s axle, and because one end of the string is attached to your finger, the yo-yo is forced to rotate as it drops. If the yo-yo could not rotate, it would not drop.
What is sleep time on a yoyo?
Responsive ball bearing yoyos have a sleep threshold of 5-45 seconds. Again, if you drop your yoyo and it sleeps for at least 5 seconds, most likely there is no problem with your yoyo.
What energy is a yoyo before it is released?
When you hold a yo-yo in your hand, it has potential energy: it stores energy because it’s high above the floor. When you release it, the potential energy is gradually converted into kinetic energy (the energy something has because it’s moving).
What type of potential energy does a yoyo have?
When the yo-yo is held above the ground, the yo-yo has potential energy from the gravity that is already pulling it down. As the yo-yo falls, that potential energy changes to kinetic energy, which increases as the yo-yo falls down. As the toy climbs back up, the kinetic energy changes back to potential energy.
What is the relationship between potential energy and velocity?
Total energy of the object = mgh. As it falls, its potential energy will change into kinetic energy. If v is the velocity of the object at a given instant, the kinetic energy = 1/2mv2. As the fall of the object continues, the potential energy would decrease while the kinetic energy would increase.
In which case is there an increase in gravitational potential energy?
The amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds. Gravitational potential energy increases as weight and height increases.
How do you find the acceleration of a yoyo?
How fast does a yoyo fall?
As noted above, in free fall, the yo-yo should take t = √(2(0.51 m)/(9.8 m/s2), or 0.32 s to fall the same distance (and its final velocity would be v = √(2(9.8 m/s2)(0.51 m), or 3.2 m/s).
What is the increase in the rotational kinetic energy of the yo-yo?
The increase in the rotational energy of the kinetic energy of the yo-yo is, 0.207 J 0.207 textJ 0.207 J.
Can all yoyos sleep?
String tension, or how tightly twisted the string is, is very important on fixed axle yo-yos. If the string is twisted too tightly, the yo-yo cannot spin in the loop at the end and will not sleep. But if the string is not twisted tightly enough, the yo-yo will not return.
Is Baby Yoyo a boy or girl?
YoYo is the daughter and middle child of Mr. and Mrs. Schmidt. She is also the sister of JJ and TomTom.
Why does a yoyo spin?
What yoyo sleeps the longest?
The SBII holds the record for the longest “sleep”: 3 minutes and 12 seconds. When you open your new yo-yo, you may be tempted to try to jam your finger through the little loop at the end of the string. Wrong!
Why is my yoyo not sleeping long?
Is the magic yoyo V3 good?
MAGIC YOYO V3 is the best entry-level yoyo, style string trick (1A, 3A, 5A). PREMIUM SURFACE. Metal yoyo V3 made from quality aluminium 6061, stable and balanced high speed routines. Super smooth sand blasting finish surface never fade and not easy to scratches.
What is the total energy equation?
The total energy of the system of a block and a spring is equal to the sum of the potential energy stored in the spring plus the kinetic energy of the block and is proportional to the square of the amplitude ETotal=(1/2)kA2. E Total = ( 1 / 2 ) k A 2 . The total energy of the system is constant.
What is the relationship between potential energy and gravity?
Gravitational potential energy is the energy possessed or acquired by an object due to a change in its position when it is present in a gravitational field. In simple terms, it can be said that gravitational potential energy is an energy that is related to gravitational force or to gravity.
What is the difference between kinetic and potential energy?
Potential energy is the stored energy in any object or system by virtue of its position or arrangement of parts. However, it isn’t affected by the environment outside of the object or system, such as air or height. On the other hand, kinetic energy is the energy of an object or a system’s particles in motion.
What are the parts of a yo-yo and how do they work together?
Background. A yo-yo is a toy that has two disks connected together and sandwiching a long string. Traditionally made of wood, the disks are now commonly made of plastic. Attached to the center of the disks, the string winds, unwinds, and rewinds, while attached to a person’s finger.
Is a yoyo a wheel?
A yo-yo – which is a simple wheel and axle machine – is the basis for several compound systems.
At what point in the pendulum is the potential energy maximum?
Where is the potential energy of pendulum at its highest? The potential energy of a pendulum depends on its height above its rest position. At the pendulum’s highest point it is at its maximum above the equilibrium point and has only potential energy.
Does potential energy change with speed?
As the velocity increases, the electron will gain more kinetic energy, and its potential energy decreases.
