Projectile Motion and Parabolas - Science of NFL

What is the shape of the arc that a football makes as it flies through the air?

• Circle

• Triangle

• Parabola

• Square

What are the two main components of velocity affecting the ball during its flight?

• Vertical and horizontal

• Forward and backward

• Left and right

• Up and down

What happens to the vertical velocity vector of the ball as it flies upwards to reach its peak?

• It remains constant

• It increases

• It decreases

• It becomes zero

At the highest point of its trajectory, what is the vertical speed of the ball?

• Zero

• Maximum

• Minimum

• Constant

What is the goal of a punter in terms of the ball's hang time?

• To make it as short as possible

• To make it as long as possible

• To make it unpredictable

• To make it spin

What happens to the magnitude of the vertical component of velocity as the ball comes back down to the ground?

• It remains the same

• It increases

• It decreases

• It becomes zero

What is the shape of the arc that a parabola can have?

• Only one shape

• Multiple shapes

• Infinite shapes

• No specific shape
