In karate, why is it advantageous to apply a force for a short time?

Explanation:

From momentum perspective,

F =∆p / t

Where p is momentum

So, the force is inversely proportional to the time taken, so the shorter the time of impact, the higher the force impact.

So, it is advantageous to apply force for a short time and the major advantage is that the punch will have a heavy impact on the opponent and with that he might knockdown his opponent.

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
