In everything that we do, there is some facet of natural philosophies involved in it.

Even if we are merely standing still on the land, or tilting up against a wall,

there are still legion forces moving upon us. This paper will state of the

natural philosophies involved in throwing a yo-yo.

When you release a yo-yo, gravitation Acts of the Apostless on its centre of mass to draw the

yo-yo downward. Because the twine of the yo-yo is wrapped around the yo-yo & # 8217 ; s

axle, and because one terminal of the twine is attached to your finger, the yo-yo is

forced to revolve as it drops. If the yo-yo could non revolve, it would non drop.

Merely as any object falling in a gravitative field, the rate of bead

additions with clip ( it decreases 9.8 metres every second to be exact ) and so,

needfully, does the rotary motion rate of the yo-yo.

The rate of bead and the

rotary motion rate are greatest when the underside is reached and the twine is

wholly unwound. The whirling yo-yo contains rotational kinetic energy taken

from the gravity potency energy through which the yo-yo has dropped.

Normally, the twine is tied slackly around the axle so that the yo-yo can

continue to whirl at the underside. Because the full length of the twine has been

laid out, the yo-yo can drop no farther and, accordingly, the rotary motion rate

can non increase further. If left in this status, the clash between the

axle and the twine will finally disperse the energy

Wallin, 2

of rotary motion or, equivalently, the rotational kinetic energy of the yo-yo and

the yo-yo will come to rest.

However, a fleeting jerk on the twine causes the clash between the twine

and the axle briefly to increase so that the axle no longer faux pass within the

twine. When the axle stops stealing, the rotational kinetic energy of the

whirling yo-yo is big plenty to ca

use the twine to weave around the axle. This

causes the yo-yo to get down to “ mount ” back up the twine. After the

foremost one or two rotary motions, the twine can no longer faux pas, so the procedure of

mounting up the twine continues beyond the fleeting application of the jerk.

As the yo-yo continues to mount back up the twine, the angular impulse

( rotational kinetic energy ) of the yo-yo is converted back into gravitational

possible corresponding to the increasing tallness of the centre of mass of the

yo-yo. For this ground, the yo-yo & # 8217 ; s rotational kinetic energy and, therefore, its

rotary motion rate, steadily decreases as the yo-yo rises. This is, of class, the

contrary of the procedure when the yo-yo was dropped.

If non for frictional losingss, the yo-yo would mount all the manner back up the

threading to your manus merely as its rotational rate lessenings to zero. But, due to

clash, the yo-yo does non rather do it all the manner back up to your manus

before it stops revolving.

Thereafter, the procedure repetitions, with the yo-yo returning short of its

old tallness on each rhythm. Finally, the yo-yo comes to rest at the


Of class, as everyone knows, it is possible to maintain the yo-yo traveling

indefinitely by giving it a little upward pull on each rhythm. This pull can be

combined with the jerk required to originate the ascent back up the twine. The

pull serves to give the centre of mass of the yo-yo a small excess kinetic

energy to counterbalance for frictional losingss, so that the

Wallin, 3

yo-yo can be kept traveling indefinitely.

Yo-yo can besides be thrown horizontally, or launched in other waies. The

rule of operation is so merely the same except that the kinetic energy of

the centre of mass, which is converted into spin as the twine unwinds, consequences

from being thrown, instead than from falling through a gravitative potency.
