the ball, there will be greater acceleration, and that translates to greater force, or more energy transferred into the football. The acceleration caused by gravity is constant, so the only thing that can change acceleration in this case is the strength the quarterback uses to throw the football.

Here’s another way to look at the equation. Football players are really careful about how much body mass they have. Depending on the position they play, too little or too much mass can affect their performance. For linemen, having a lot of mass is a good thing because it directly impacts the force they’re able to use in plays. For receivers, having too much mass is not such a good thing, because it directly affects the acceleration they use to run down the field. Ball Placement I f you’re a football fan, you can probably easily recall the greatest catch you’ve ever seen. Maybe it was a great play right at the end of the game to win it. It seemed like time stopped as the fans watched the ball float through the air. Then, the ball lands in the hands of the receiver—and the crowd goes wild! Let’s examine the science behind ball placement for amazing plays like that one. Recall Newton’s First Law: an object will continue on its path unless an external force acts upon it.
