I’ve been a Physics experiment this week! 😉
We’ve been working on sweeps from open guard and spider guard this week. These positions always make me nervous. I’m afraid that I’ll drop the guys on top of me. But, things were different this week. I learned that in these positions, I can use gravity to my advantage.
I have a very difficult time sweeping the big guys when they are in my guard. They root their bums to the ground like ancient oak trees. I realized today that, in this position, they have gravity on their side. This is my “Evil Gravity”! 😦 Now, if I’m in spider guard, I can load the weight of the guys onto my legs. Being a woman, my lower body is stronger than my upper body. Also, I have my back on the ground giving me the support of the world, literally. In this position, their center of gravity is shifted forward. Now, they are off-balance. All I have to do is tip them to one side or the other. Gravity takes over from there. This is my “Happy Gravity”! 🙂
Newton’s first law of motion states that an object continues in its state of rest unless compelled to change by an external force ( me and gravity). The object will continue with a constant velocity unless compelled to change by an impressed force ( Earth ). ( see Linda Huetinck, Ph.D. “Physics” published by Cliff Notes, 1994, Lincoln, Nebraska, p 19)
The other sweeps we drilled were from open guard. You’re partner is attempting a standing guard pass. Here you would grab your partner’s sleeve and sweep his legs with your legs. Don’t let go of the sleeve! The object is to let the force created by your partner’s fall backward, pull you through their legs and into side control. 😉 My partner outweighed me by fifty pounds (22.7 kg) So, when he would fall back all of that extra mass would catapult me through his legs and right into side control. With an americana setup, I might add! However, my fall backward didn’t create enough force to pull my partner through my legs into side control. This is directly caused by my lack of mass. Poor guy… He is so nice, too.
Newton’s second law of motion states that if a net force acts on an object, it will cause an acceleration of that object. The law addresses the cause and effect relationship between force and motion ( F = ma) Force = F, mass = m, and acceleration = a. (see Huetinck again) So, you take my mass and multiple it by my acceleration, you would get “Jodi Force”. Now you take Nice Guy mass and multiple it by his acceleration, you would get “Nice Guy Force”. Please note, that since Nice Guy’s greater mass will cause a greater acceleration for him. So, Nice Guy’s greater mass and acceleration created a greater force, which I used shamelessly! 😉
I’m looking forward to hearing from you guys. Please let me know if my train of thought is going in the right direct. It lacks a compass most days.
