Newton's First Law of Motion in Football

What is the main goal of offensive players in the NFL?

• To stop the defender's forward progress

• To change direction and speed

• To get down-field as far and as fast as possible

• To exert an unbalanced force on the defender

What is the main goal of defenders in the NFL?

• To stop the offensive player's forward progress

• To change direction and speed

• To get down-field as far and as fast as possible

• To exert an unbalanced force on the offensive player

According to Newton's First Law of Motion, what happens to an object at rest?

• It requires an unbalanced force to make it not be at rest

• It tends to stay in motion in a straight line at a constant velocity

• It changes direction and speed

• It exerts an unbalanced force on other objects

What is the term used to describe a player's natural resistance to an unbalanced force?

• Inertia

• Gravity

• Mass

• Velocity

What does a player's mass determine in terms of inertia?

• How strongly an object's mass is attracted by gravity

• How much matter an object has

• How fast an object is moving

• How hard it is to move the object off its path

What is the difference between mass and weight?

• Mass is a measure of how much matter an object has, while weight is a measure of how strongly an object's mass is attracted by gravity

• Mass is a measure of how strongly an object's mass is attracted by gravity, while weight is a measure of how much matter an object has

• Mass and weight are the same thing

• Mass and weight are not related to each other

What determines the winner in the battle between players in the NFL?

• The player with the most mass

• The player with the most speed

• The player with the most agility
