Where is Math/physics used in football?

Question

Im doing a research paper and would like some suggestions. If i could get links that would be greatly appreciated

I am gathering information for a Math research Paper in 3H aka 11 honors math. any links will be greatly appreciated. Thank you

Answer 1

the following are some useful links

Answer 2

1. Anything about the motion of the ball.

2. Anything about whether a running back will fall forward or backward when hit, and similar issues.

3. The angle of pursuit when trying for an open field tackle.

4. Von Neumann's min-max (aka minmax) theorem for two-person zero-sum games!! That one's trickier, but it absolutely applies. Ideally, the defense tries to arrange things so that each of a quarterback's several choices during the unfolding of a play is equally bad. If that's not the case, the QB will (ideally) choose his best option, and be better off than if the defense had done it right. That's straight out of game theory. And the same applies on offense, e.g. on play-action.

Answer 3

Like the others were saying, physics could be applied with motion of the football and football players (including angles, force, and distance)... You could also apply simpler mathematics using the distance that a ball is thrown or a player runs... Every time they measure how far the ball got, the chain gang have to be precise... Also, in order to figure out how many yards the play has to go, you have to subtract how many yards the team went the previous play from how many they needed to go... If they lost yards, you have to subtract a negative number and if they gain yards, subtract a positive number... Ex: If it is 1st down, 10 to go and the team gains 2 yards, then it is 2nd down, 8 to go (10-2=8). If it is 1st down, 10 to go and the team loses 2 yards, then it is 2nd down,12 to go (10 - (-2) = 12)...

Just so you know, I am a math and science teacher. :)

Answer 4

Physics/Math Football Question?
=========================
The launching velocity of a projectile is 20 m/s at 53 degrees above the horizontal. A. What is the vertical component of its velocity at launch? B. Its horizontal component of velocity? C. Neglecting air friction, which of these components remains constant throughout the flight path? D. Which of these components determines the projectile's time in the air?

If you could please write the answers and explain it would be great :) I find it very difficult to understand. Thank you!

just for reference
g=32.2ft/s²
r=unknown

Θ=0.5 * ((invsin)(r*g/v.²))
2Θ=((invsin)(r*g/v.²))
2Θ*v.²=((invsin)(r*g))
sin (2Θ*v.²)=r*g

Vy=15.96
Vx=12.036

therefore
sin (2Θ*v.²)/g=r
and
sin (2Θ*v.²)/r=g
--------------------
first thing u do is look at the question
of course
u have 2 angles
1./ 53º
and
2./ 90º-53º=37º
you are given the resultant speed(hyp)
so now u have to find
the compotent speeds
there are 2
speed(Y)
and
speed(X)
so lets find both
53º above the horizon
therefore

20 * cos(53º)=speed(X) or 20 * sin(37º)=speed(X)

20 * sin(53º)=speed(Y) or 20 * cos(37º)=speed(Y)

so

20 * cos(53º)=speed(X) or 20 * sin(37º)=speed(X)
20 * 0.6018 =12.036

20 * sin(53º)=speed(Y) or 20 * sin(53º)=speed(Y)
20 * 0.798 = 15.96
now we have speed(Y) = 15.96
v= g * t
v = 32.2 * 0.4956
v = 32.2 * 0.4956
v =15.96 or speed(Y)

lets find distance to drop from the sky to ground

d(Y) = 0.5 * g * t²
d(Y) = 0.5 * 32.2 * (.4956)²
d(Y) = 7.97ft or distance(Y)
---------------------------
now u can calculate the Range
----------------------------
d(X) = speed(X) * t
d(X) = 12.036 * .4956
d(X) = 5.965 ft

Carry on from here now
if u cant see this now
take up social science or politics

Answer 5

well physics is applied every time a tackle or line man go head to head,, need someone of the same size to stop the forward momentum, also if a receiver is running at X how long will it take him to finish the pattern,

Answer 6

it's used by the statisticians and the other people who are not capable of being on the field to fancily describe the actions that are occuring on the field...in football you just play the game if you can...and if you can't but don't want to be left out of it for whatever reason, you tell them they ran down the field in 10.87 seconds in order to have something to say

Answer 7

when the ball is thrown thats projectile motion in physics....momentum also...you may need to calculate the angle and the force at which you throw the ball in order t o reach your receiver

Answer 8

taking frees the angle that is needed to hit the top left corner for example or what part of the ball and what force you need to curve the ball

Answer 9

for the shape of the ball,volume of the ball,width of football ground,goal post,mass of the ball,thickness of ball,amount of air inside the ball.

Answer 10

in the yard and timed plays.
