Beyblade Experiment: What affects Momentum?

Share with your friends!

About a year ago, my son and I ran an experiment with his favorite toy, beyblades. The spinning toy is still a favorite in our house, with the younger two boys joining in on the fun! For Christmas, we gave our oldest a beyblade type toy that had some difference features than his other ones. We decided to rerun the experiment we had done before, but this time with his new spinning top toy!

What affects Angular Momentum? My son's and I run a simple momentum experiment using Beyblades!

The toy we bought my son was actually called Metal Master Fusion Storm. The pack included four spinning top beyblades, and a few launchers. We set off to repeat our previous experiment, but this time with the new toy!

Beyblade Experiment



Step 1: We picked one of the bey spinning top toys from the package Metal Master Fusion Storm box. We weighed the toy, and timed how long it took for the toy to stop spinning.

Step 2: We picked 4 of my son’s beyblades to compare our new toy with, one attack, one stamina, one defense, and one balance.

Step 3: We repeated step 1 with each of the beyblades from STEP 2.

Our Metal Master Fusion bey blade some what followed the same angular momentum trend we had found in our previous experiment. In the previous experiment, we found that the more a beyblade weighed, the more angular momentum it had, and the longer it took to stop spinning. The Metal Master Fusion predictably stopped spinning in less time than the Stamina, Defense, and Balance beyblades, since it weighed less than the three beyblades at only 1 oz. But what was unexpected was that, while it weighed less than the Attack type beyblade, the Metal Master Fusion still spun longer.

To better understand our results, we looked back at our videos of the two beyblades.

Here is a video of one of the Metal Master Fusion’s runs:

And here is a video of the Attack type beyblade:

As you can see from the videos, the two beyblades act very different as they spin. The Metal Master Fusion spins pretty much in the same place as where it was released. The attack type beyblade, on the other hand, races around the stadium from side to side, until it starts slowing down. The reason it stops sooner than the Metal Master Fusion spinnning toy is because each time it hits the side of the stadium, the beyblade loses kinetic energy. Losing kinetic energy slows down the beyblade, until it eventually stops.

This begs the question, why does the attack type beyblade behave the way it does? But that is another experiment for another day.
