To be considered a sack, the quarterback must intend to throw a forward pass. If the play is designed for the quarterback to rush (run) the ball, any loss is subtracted from the quarterback's rushing total (and the play is ruled a tackle for loss as opposed to a sack).
- Force Equal Mass Times Acceleration

- Center of Mass
Newton’s second law refers to the fact that force is the equivalent of mass multiplied by acceleration. Mass is, obviously, the weight of the player, plus the extra pounds that protective gear like padding and the helmet add to the body. Acceleration, however, isn’t just a measure of how fast the tackler is moving — it also has to take into account...
According to Newton’s third law of motion, total momentum — mass multiplied by velocity — remains constant in a closed system. (You’ve probably heard this one recited as “Every action has an equal and opposite reaction.”) When two players are on a collision course towards each another, a maximum force tackle is about to occur; if the mass is relati...
Torque refers to rotational force, which governs both sports (and non-sports, actually). And it can be a big part of how a tackle is made in football. See, a sack won’t necessarily be a clean thing to behold. It might involve having to physically wrestle the quarterback down to the ground by way of swinging his body. A tackler will have more torque...
A player’s center of mass is the point where gravity acts on his body. This is alwaysat the torso. It’s why shorter people exhibit lower centers of mass and taller people possess higher centers of mass. When the center of mass is closer to the ground, the potential torque is smaller. It’s much harder to be swung to the side and towards the ground c...
Rice had 5 tackles and 2 sacks in the Super Bowl and 15.5 sacks on the season, including 11 sacks in a 5-game span. Over the next 3 seasons, the Buccaneers only had one with a winning record and lost the only playoff appearance they had.
Sep 10, 2020 · A sack occurs when a defensive player makes contact with the QB, who is then ruled down by contact. Therefore, it is not technically required that the QB is “tackled”. A sack also occurs if the passer runs out of bounds behind the line of scrimmage following defensive pressure.
Jun 27, 2018 · Rice’s line through three quarters: two run stuffs, a hurry of league MVP Rich Gannon that forced the first of a Super Bowl-record five interceptions, and three sacks—the last of which came on...
Aug 29, 2024 · A sack is also registered to the defense if the quarterback (or passer) is forced out of bounds behind the line of scrimmage due to pressure. Sacks result in a loss of down for the offense and can force the line of scrimmage to move back several yards.

Sep 5, 2024 · A sack occurs when a defensive player tackles the quarterback behind the line of scrimmage before he can throw a forward pass or hand off the ball. This usually happens when the offensive line fails to adequately protect the quarterback from the pass rush.
