This presentation is about goal line technology and vanishing foam

2. INTRODUCTION
In this presentation, I will tell you about how
science and technology have changed the game of
football . I will also show you how the various
technological rules and regulations implemented in
the game have created buzz around the world.

3. ACKNOWLEDGEMENT
 I WOULD LIKE TO MY THANKS MY
MENTOR FOR GIVING ME AN
OPPURTUNITY TO MAKE A
POWERPOINT PRESENTATION AND
PRESENT IT IN FRONT OF MY
FRIENDS AND FACULTIES. I
WOULD ALSO LIKE TO THANK
SOME OF MY FRIENDS IN HELPING
ME MAKE THIS PRESENTATION.

5. Goal line technology
Goal-line technology is a method used to
determine when the ball has slightly crossed
the goal line with the assistance of electronic
devices and at the same time assisting the
referee in awarding a goal or not.

6. It’s Inclusion
 Questions arised to include it in the
game during 2000
 Referee gave wrong decision for the
penalty shootout
 Match was played between Nigeria
and Cameroon
 Ball had actually crossed the line but
refree denied it
 Nigeria lost the game.

7. On 5 July 2005 , IFAB officially approved the use of goal
line technology. The two systems approved in principle
were involved in test phase 2:
Goal Ref
 Electromagnetic
induction
 Ball has special
copper coils in it
 Notifies ref within 1
second via watch
Hawk Eye
 6 Cameras focused on
each net
 Predicts where ball will
go
 Notifies ref within 1
second via watch
Technology Estimated cost per
stadium
Goal Ref $ 250000
Hawk Eye $ 325000

9. It’s objective
To support the role of
referees
 Not to replace referee’s role
To provide clear decision
Help referee in making final
decision

10. FIFA REQUIREMENTS
-Only used in goal situations
-Must be accurate
-Referee notified of the goal within one
second
-Indication of goal only committed to
Referee

11. Advantages of GLT
= More Accurate Calls
= Modernize Sport
=Reduces Human error factor
=Referees can overrule the
technology

12. Goal line technology in World
Cup 2014
-This time the game between France
and
Honduras in group stage was decided
by
the goal line technology.
-France beat Honduras by 3-0 in which
one
of the goal was decided by GLT.
-The goal was scored by Karem
Benzema

14. DISADVANTAGES OF GLT
 Technology is not 100% accurate.
 Its installation is very costly.
 It ruins the heart and soul of the game.
 Some older fans are more reluctant to
trust technology in making those kind
of goal decisions.

15. Brazuca
-Official ball of Fifa 2014 world cup
-Made by Adidas Scientific Research
centre
-Made from polyurethane
-Improved grip, touch, stability and
aerodynamics on the pitch
- Increases the speed of the game

16. Science in making Brazuca
 Has six polyurethane panels
 All are bonded to keep the ball of
same weight and roundness
 Even in the heaviest of rain it retain its
roundness
 Provides faster flight speed
 Maintains true roundness

17. Description
- Bladder of brazuca ball is made of
latex
- Provides the desired rebound
- Highly textured
- Feels like adidas’finale used in 2013
UEFA
- Available in bold white, night
blue,multicolor
- Most colourful ball ever

19. Stats: Weighs 437 grams and has a low absorption rate,
meaning it can retain shape and weight even in rain.

20. Vanishing Foam
-Vanishing foam is a new technology used in
football.
-Foam is applied as a line during free kicks and
Penalty shootouts
-Helps referee in checking the player if he
crosses the marked distance

21. ADVANTAGES
 Prevents unnecessary delay
 Prevent unnecessary delays by
preventing the defensive team from
encroaching closer
 Prevents the attacking team from
illegally moving the ball from the spot
