Brazilian Jiu Jitsu and physics

Introduction

Jiu-Jitsu is a grappling style martial art that uses physics to manipulate the opponent’s body using forces, torque, leverage, and fulcrums. Torque is a rotational force, leverage is found when a force is applied on a lever point, and fulcrums are found where a lever is supported at a point where it can pivot.

Why does Jiu-Jitsu follow this progression?

  1. Get your opponents to the ground
  2. Get past your opponent’s legs (or attack their legs)
  3. Control their hips and shoulders (or their legs)
  4. Add a submission

Jiu-Jitsu follows this progression because on the ground there is less leverage for the opponent to use against you as your center of balance is closer to the ground. Then you must get past their legs because those are the longest, strongest leverage points and most powerful tool to their body. Next, you control their hips and shoulder because that is where their center of gravity is. After all this, you can manipulate their body to submit them

Why does Brazilian Jiu-Jitsu want to control?

Brazilian Jiu-Jitsu wants control because when you are in control you can force your opponent to submit by manipulating their body until you win the match.
