If you throw him with a larger force, he will fall faster to the mat. If he strikes his body against yours to push you down backward, the larger his body, the more difficult it becomes for you to stop his body's movement before he applies his throw.
These phenomena are all due to the second law of motion. It is this law that shows us why a large man has an advantage over a small man in competition.
Third law of motion
The third law of motion is called the law of reaction. The law states that to every motion there is a reaction. We find numerous examples of this in our daily experience. If a man in a rowboat pushes another rowboat, the pushed boat moves in the direction of the force applied, while the pushing boat simultaneously makes a corresponding motion in the reverse direction.
Again, if a man in a boat pushes the shore with a pole, his boat gets clear of the shore. If a person standing in a natural posture before a pillar pushes it with his hand, he will tend to fall backward. This is due to the force of reaction that the pillar exerts against his force.
The third law of motion—the law of reaction—proves that a dynamically produced force is more important than the force of the muscles in breaking the posture of the opponent and making him fall as the result of a fast and powerful movement of your body.
In grappling, why is it difficult for your opponent to get up when he is turned over on his back? It is because he has nothing to push against effectively with either of his feet. Consequently, he can use only the force of his arms and shoulders, but this is not enough to make all parts of his body cooperate.
