Introduction to “BeyPhysics”

In Beyblade, Physics is often used to aid competitive players. Competitive customs are made because of Physics. For example, why do most stamina customs have their weight externalized? Often, players will build a competitive custom without knowing what its true use is.

Physics
Competitive Customizations often incorporate Physics.

Use of Physics in Smash Attack Combinations: In Competitive Smash Attack Combos, one of the basic fundaments of physics can is applied: "As an example of varying pressures, a finger can be pressed against a wall without making any lasting impression; however, the same finger pushing a thumbtack can easily damage the wall. Although the force applied to the surface is the same, the thumbtack applies more pressure because the point concentrates that force into a smaller area." This basic fundament states/determines why a MW like Flash is used for attack rather than a MW like Duo. Flash has several small notches on the perimeter of its MW. It is these small notches that focus force into smaller points, creating more pressure and allow for critical hits. The Weight distribution of a smash attack combo should be focused towards the MW’s perimeter. While focusing weight towards the center may give a higher spin velocity, this isn’t much use to Smash Attack Customs. A higher Spin Velocity does not necessarily equal a more powerful attack. Spin Velocity and Rotational Velocity are different things. Spin Velocity constitutes the amount of revolutions per unit time. Rotational Velocity is the linear speed component of a given point on a rotating body at a given instant. Spin Velocity creates Rotational Velocity, and Rotational Velocity is what creates Rotational Inertia, which is what assists in Attack (given a point on the perimeter of the spinning body.) Spin Velocity can increase Rotational Velocity (MF), though to do so in Beyblade is less efficient than increasing your Rotational Inertia through outside focused weight. Rotational Inertia is the force behind an Attack, (Rotational Inertia is basically a combination of Rotational Velocity and Mass.) In the realm of Attack, Spin Velocity is never a bad thing, but never should Rotational Inertia be forgone in its sake.

Use of Physics in Upper Attack Customs- Although Upper Attack is irrelevant to the MFB metagame, Physics still impacts many customs using Upper Attack. Upper Attack Beyblades should be focused on maintaining a high spin velocity as well as being low in height. If the opposing Beyblade has a higher spin velocity, then in will be harder/more difficult to lift them (which is the main purpose of Upper Attack customs.) Thus, it is necessary to make a Upper Attack Custom as Low and as Heavy as possible.

Use of Physics in Force Smash Customs- In Force Smash customs, weight generally needs to evenly distributed in order to maintain a higher spin velocity. The Beyblade utilizing Force Smash must be tall also.

Use of Physics in Weight Based Defense Customizations- Competitive defense customizations often rely on high spin velocity to survive heavy hits from attack type Beyblades. For weight based defense customs, generally the heavier an object is, the harder it is to move that object. For example, an attack custom such as (MF Flash Pisces S130 R2F) would have a very hard time knocking out a defense combo such as (MSF-H Wyvang Wyvang BD145 MB/CS). Additionally, more weight means higher spin rate.

Use of Physics in Grip Based Defense Customizations- Grip Based defense customs apply a tremendous amount of friction. Generally, the more friction an object has, the harder it is to move it. For example, an attack custom such as MF Flash Pisces GB145 R2F will have a hard time KO’ing
MSF-H Revizer Revizer E230 CS.

*The Use of Spin Velocity in Attack and Defense Customs- Spin Velocity makes a Beyblade complete more spins whereas Rotational Inertia allows a Beyblade to retain spin and make its Attack and Defense Better. This is why most Defense Customs and some Attack Customs use a MF-(H)/MSF-(H).

*The Use of Spin Velocity in Compact Customs- Although irrelevant to MFB, compact customs incorporate Physics as well. A compact combo focuses on having high spin velocity. The shape of compact combos are generally small and thus, compact. The majority of a compact combo’s weight should be distributed toward the center. As a result of this, compact combos have incredibly high spin velocities.

The Use of Physics in Stamina Customs- Competitive Stamina Type Beyblade’s have their weight externalized around the perimeter. Most Stamina Metal Wheel’s have a hollow and light center. As a result, this produces what is known as the Flywheel Effect, which is the ability for a rotating object to increase its rotational velocity with the use of its own momentum. The flywheel effect is the continuation of oscillations in an oscillator circuit after the control stimulus has been removed. It should be noted that Rotational Inertia retains spin, NOT Spin Velocity. That is why most good stamina wheels are fairly wide. Stamina customs (usually) use a MF-L to keep their weight externalized.


* Real World Example of Rotational Velocity:- Spin a ball or a coin or virtually anything. It will complete vastly more revolutions per unit time than the Earth does, but the perimeter of the Earth is moving much faster (1037.5646 mph/1669.8 kph). Would you rather get hit with a beam moving at that speed or the speed of the perimeter of your ball? Yeah. Obvious answer. That’s Rotational Velocity. The force behind the hit is increased with outside-focused weight, so the wider and heavier (on the perimeter) the better.


Overall

Physics has impacted Beyblade from the very beginning. It plays a key role in determining which Beyblade’s are competitive and which ones aren’t. As a result, every competitive Blader should have an introductory understanding of Physics before building a competitive Beyblade combo.

I realize another thread like this had been made previously. I believe that this thread has more applied Physics information .
Eh, just post this in the Beywiki Physics topic, since we will probably not do one big article for all the physics involved in Beyblade. I also already made a draft about the Flywheel Effect, which is what you seem to be talking about most of the time.
