How do you find the acceleration of a yoyo?
Why does a yoyo go up and down?
It builds linear momentum, which is the momentum to keep going straight up and down, and it also builds angular momentum, which is the momentum to keep rotating. Going up and down, a yo-yo continually cycles between having potential energy and having kinetic energy.
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 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.
What does it mean if the torques on an object add up to zero?
If the net torque on a rotatable object is zero then it will be in rotational equilibrium and not able to acquire angular acceleration.
How do you make an unresponsive yoyo come up?
Why did my unresponsive Yoyo become responsive?
The yoyo will become responsive, and/or the bearing will suddenly start making a different noise. This is usually due to dust or hair entering the bearing. It is completely normal and happens quite often. Unscrew the yoyo carefully, remove the string, and spin the bearing.
How do you make a responsive yoyo unresponsive?
Why can’t I wind my yoyo?
On yo-yos with bearings, if you try to wind it up, it will just spin and won’t wind. To wind this kind of yo-yo, use your thumb to pin down the string against the inside edge of the yo-yo whilst winding.
How do unresponsive yoyos work?
What forces are acting on a yo-yo?
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.
Is Yoyo potential or kinetic energy?
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.
At what point on a roller coaster is the kinetic energy increasing?
At the highest point on the roller coaster (assuming it has no velocity), the object has a maximum quantity of gravitational potential energy and no kinetic energy. As the object begins moving down to the bottom, its gravitational potential energy begins to decrease and the kinetic energy begins to increase.
How old is the yo-yo?
A toy that has been dated back as far as 440 BC. It is believed that the yo-yo originated from one of three countries: China, the Philippines and Greece. However, the oldest historical mentions and artifacts that have been found are from Greece.
How do light up yo-yos work?
How does the string of a yo-yo get the yo-yo spinning?
The yo-yo is held up in the air, giving it the potential to fall to the ground. The yo-yo has string wound around it, giving it the potential to spin as it unwinds.
Does a yoyo bounce?
When a yo-yo that has a string wrapped tightly around its axle reaches its full extension, it automatically bounces back upwards, the string re-winding in the process.
How do you tell if torque is clockwise or counterclockwise?
What is the force that when all the force are sum up will equate to zero?
The vector sum of all of the forces acting on a body is a single force called the net force . If the net force is equal to zero, the object is said to be in equilibrium.
What is r in torque formula?
The distance from the pivot point to the point where the force acts is called the moment arm, and is denoted by ‘r’. Note that this distance, ‘r’, is also a vector, and points from the axis of rotation to the point where the force acts.
Can you put a responsive bearing in an unresponsive yoyo?
2. Unresponsive Yoyo : Adopt 8 ball KK bearing, you can replace the bearing from responsive bearing (narrow size C 8 ball bearing) to a professional advanced unresponsive yoyo, just simply use our professional bonus removal bearing tool!
What is the fastest way to wind an unresponsive yoyo?
Do they still make Duncan yoyos?
We’ve been making them since before your parents were born, and maybe even some of your grandparents! Duncan may have been around for a long time, but we have still managed to keep up with the times. Whether you’re looking for a high tech modern competition level yo-yo or a classic Imperial, you can find it here.
