If a professional football player ran at you and collided with you, what would happen? Why? Use the terms force, mass, and velocity in your explanation.

the force of the football player would cause you to fall over and possibly get a concussion because the football players mass is probably more than yours and the velocity of the football player would cause you to fall over or in football terms "get tackled"

Explanation:

Newton stated within his first law of motion that any object of mass at rest (velocity, designated as v, is zero) will tend to stay at rest, and any object in motion (velocity is not zero) will tend to stay in motion at the same speed and direction (acceleration, designated as a, is zero), unless acted upon by a force.  Applied to football collisions, the more massive a football player (the more he weighs), the less likely he is to be slowed down, sped up, or diverted by an outside force, such as opponents. The first law is often called the law of inertia because the term inertia means the resistance to motion. For instance, the quarterback who desires to score a touchdown when very near to the goal line will often use the quarterback-sneak. In this scenario, the interior offensive line of players is used as a massive wall to block the defensive line so the quarterback can sneak around or over his men who are very resistant to being moved back.

the device is called “ rocket engine”
