Before and after design of a yo-yo.3
A yoyo works by converting potential energy into different kinds of energy as it falls down. When the string is tightly wound around the axle and the yoyo rests in the person’s palm, the yoyo has a lot of potential energy. The potential energy is turned into the two of the following: gravitational energy and the potential to spin as it unwinds.
When the yoyo is allowed to fall, the potential energy turns into kinetic energy giving the yoyo linear momentum and angular momentum. Since the yoyo is falling straight towards the ground, this is called the linear momentum. The linear momentum can be calculated using a simple formula p=mv Momentum = mass * velocity. As the spring unwinds, the spool spins which creates angular momentum. Definition of angular momentum is “a quantity associated with how an object moves around a... [continues]
