no you are miss applying it, we are talking about newtons laws of motion, which don't lend themselves to being explained in forum posts, so here is some reading Force - Wikipedia in,short, force is the effect an interaction has on the objects involved, so at its simplest, lets take the kicking of a football. kinetic energy is what you are using to strike it, force is what happens to the football, it has constant mass, so the key point is the acceleration of the object you have hit, not the speed of your foot in hitting it. So you would take the weight of the football and times that by its rate of acceleration to find the force you have generated. If you miss kick and skim the ball. The kinetic energy and speed of your foot is the same, but the force generated in the football is considerably less if you have made an error in judgement, and kicked a ball made of stone, it won't move, so the force applied os the weight of the stone ball times the deceleration of your foot. all forces being equal and opposite you will break your foot so... To measure force you measure the effect on the objects being contacted Not the speed or mass of the body striking the object .
