Final answer:
The change in field position for the football team that lost 4 yards on two plays can be represented as a total loss of 8 yards. Football players are advised to keep their feet on the ground to maintain better control and leverage, making use of momentum, work, and energy principles. A 100-yd-long football field converts to approximately 91.44 meters.
Step-by-step explanation:
The question regarding the football team losing yards on successive plays relates to a mathematical representation of the change in field position. In American football, a yard is a standard unit of measurement, and one yard is approximately 0.9144 meters. Since the team lost 4 yards on two plays in a row, the change in field position could be represented as a negative movement twice, resulting in a total loss of 8 yards from the initial line of scrimmage.
When coaches advise players to block, hit, and tackle with their feet on the ground, they are referring to the concepts of momentum, work, and energy. A player has better control and can use the ground as leverage, making their actions more effective and powerful compared to leaping through the air, which can lead to decreased stability and force.
For the measurements on the field, converting yards to meters, a 100-yd-long football field would be approximately 91.44 meters long as 1 yard is equal to 0.9144 meters.
