A 250 g yoyo is swung on the end of a 50 cm string at a constant speed of 4 ms The centripetal force acting on the yoyo is?
It's either the axiom or the velocity of the swinging motion.....of course the yoyo must be goin in a full loop or circle (not the yoyo spinning itself) to act on it... other than that im almost 80% sure im right.
What are the forces exerted on a yoyo hanging motionless on a string?
The string n the yo yo r even in newtons I think -Cisco
What are some cool science fair projects involving a yoyo?
see how string length affects overall spin time
How does a yoyo work?
it depends a imperial shaped yo yo's shape lets it roll back up immediately when u tug the string a butterfly shaped yo yo's shape lets it land on the string with unique tricks the bearing on both butterfly and imperial yo yo's are meant to stay at the center the bearing's smooth texture lets the string wold on to it when you throw the yo yo the bearing will make the yo yo spin the string will hold on to the bearing with out stop the yo yo from spinning then you simply tug the yo yo back up and catch it with your hand
How does the yo-yo work?
It's kind of like a rubber band, except your hand is the rubber and the string is the band. The momentum of the yoyo going down and you snapping your wrist makes it go back up.
How do you do a long sleeper trick on a yoyo?
Rub candle wax into the string to give you a longer rotation time. Also take some of the string twist out of the string so it has less braking action. Assuming that you're right handed, you get the yoyo spinning as fast as you can, then reach down with your right thumb and index finger to pick the yoyo up about 3 inches from the spinning yoyo itself. Your left hand thumb and index finger will form the bottom of a triangle, while your right hand's middle finger will form the top of the triangle of string. The yoyo is then swung in and ouy of the triangle of string. It takes some practice.

How is the yoyo played?
spinning
What pulls a yo-yo back to the top?
Centrifugal force. The yoyo is spinning rapidly on the downswing and when it hits bottom it returns climbing the string.

What is the abbreviation for yoyo?
its a string with a ball on the end
What is the best yoyo for string tricks as in to buy ect d.m dv88 ect?
Butterfly yoyo.
What is the point in yoyo gloves?
The point of yoyo gloves is to protect your hand from string burns and to create a smoother slide for the string. It also stops the build up of grease and dirt on your hands going onto your string.
How do you fix an un breakable yoyo string knot you break up the yoyo and you take off the string 4 another if the yoyo seems to be unbreakable the stick something not sharp to take the knot out?
ok,the way you posted is ok but be extra careful because any string can be cut so be carefu
Is knots in your yoyo string about jerry spenelli?
Yes. It is an autobiography.
How do you clean a yoyo string?
you don't really. I just buy a new ones
How do you tighten a yoyo string on your finger?
put your finger through the loop and then pull.
