This document discusses the use of math in several sports. It begins by explaining the movement of a ball over a plane surface and impact times. It then provides examples of how math applies to basketball, baseball, and soccer. For basketball, it discusses variables like the court dimensions, basket height, and three point line distance. For baseball, it mentions the "sweet spot" of hitting and how a curve ball curves through the air. And for soccer, it notes that it is a game of angles between goaltending and shooting.
This presentation introduces us to the rules of Cricket and to understand the game Better

I prepared this presentation to bring up my colleagues, from non cricket playing countries ( Singapore, China & US) , understanding of cricket. Why Aussies, Brits and South Asians are so hung bo about it. We later went to play the cricket in indoor environment. Quite un-Cricket like.
A power point presentation on Football / Soccer. Briefly explaining about its rules, field dimensions,history,all-time legends,fifa ,etc with wonderful animation and pictures. Ping me at Twitter (https://twitter.com/rishabh_kanth), to Download this Presentation.
It contains every info related to football and exactly a presentation which a school needs. Hope you find it useful and hardworking. I have put videos also for a better .explaination

Mats André Zuccarello Aasen, commonly known as Mats Zuccarello, was born on September 1, 1987, in
Oslo, Norway. He grew up in the bustling neighborhood of Løren, where his passion for ice hockey began
at a young age. His mother, Anita Zuccarello, is of Italian descent, and his father, Glenn Aasen, is
Norwegian. This multicultural background played a significant role in shaping his identity and versatility
on and off the ice.

3. Issues To Be Discussed
1. The movement of a ball over a plane surface
2. Impact Times
2. Real World Application
- Basketball
- Baseball
- Soccer
4. The Movement of a Ball over a
plane Surface
Central blow over a horizontal surface
Consider a ball of mass M and radius a.
Let coefficient of Sliding friction be µ
Then friction on Ball – F= µMg (1)
This force will have 2 consequences
(i) Linear deceleration of ball
(ii) moment of force about C (centre) will produce a
clockwise angular acceleration
5. Continued
Application to billiard balls
The sliding coefficient of an average
billiard table is about 0.2, velocity
of a strongly cued ball ≈ 3ms
therefore duration of sliding phase
is = t = 2(3)/(49)(0.2)(9.8) = 0.4 secs
Using (13) distance travelled = 1.1m
6. Impact Times
In most games, experiments indicate that the linear
compression x of a golf ball is related to the applied
force F by a law of the form of F=Kx
This leads to a relation between impact times and
velocity, As velocity increases, the duration of impact
decrease, approaching a constant value at higher
velocities
7. Continued
Forces at impact
in a golf drive, velocity of ball of tee ≈70ms , time of
impact = 0.0005secs, mass of ball = 0.046kg.
By Newton (ii) (average force)
= 0.046 * 70 / 0.0005 = 6300N
This is the average force at impact since it must be zero
at the start and finish of impact, it is reasonable to
suppose that MAX force occurs at midway throughout
the impact 6300 * 2 = 12600N
8. Math in Basketball
Score Keeping
2 point, 3 point shots
Free throws
94’ by 50’ court
Basket 10’ off the ground
Ball diameter 9.5”
Rim diameter 18.5”
3 point line about 24’ from
basket
Think of any ways math can
be used in basketball?
9. Continued
Basketball Shot
At what velocity should a foul shot be taken?
Assumptions/Given:
Distance
About 14 feet (x direction) from FT line to
middle of the basket
Height
10 feet from ground to rim
Angle of approach
Close to 90 degrees as possible
Most are shot at 45 degrees
Ignoring air resistance
10. Math in Baseball
Sweet Spot” of hitting a baseball
-When bat hits ball, bat vibrates
– Frequency and intensity depend on location of contact
– Vibration is really energy being transferred from ball to
the bat (useless)
11. Continued
Pitching a Curve Ball
Ball thrown with a downward
spin. Drops as it approaches
plate
For years, debated whether
curve balls actually curved
or it was an optical illusion
With today’s technology,
it’s easy to see that they
do indeed curve
12. Math in Soccer
Soccer is a game of angles”
Goaltending vs
Shooting
13. Angles in Soccer
May think it best to stand in a position that bisects
goal line
Gives shooter more room between goalie and left post,
than right post
