The amount of power generated in a strike is fundamentally determined by two key physical variables: the mass delivered and the velocity of the strike. Mass refers to the weight of the object or body part delivering the strike, while velocity pertains to the speed at which that strike is executed. According to laws of physics, specifically the kinetic energy formula, the energy transferred upon impact is influenced by both the mass of the striking object and its velocity.

When a striker delivers a blow, the greater the mass and the faster the movement, the more powerful the impact will be. This principle is vital in defensive tactics, as maximizing both of these variables can enhance the effectiveness of defensive strikes or counterattacks.

While the angle of impact and technique, the weight of the striker and target size, as well as reaction time and impact area, all contribute to the overall effectiveness of a strike, they do not fundamentally dictate the measurable power generated in the strike like mass and velocity do. Therefore, the correct relationship that directly correlates with the power of a strike is indeed the mass delivered and the speed at which it is delivered.
