DID YOU KNOW THAT
YOU CAN LEARN PHYSICS
Start to learn about some basic science involved in this game.
It looks at the following questions:
What are some examples in football of potential energy and kinetic energy?
What is 'collision' and what does it have to do with football?
GATEWAY TO SCIENCE:
SPORTS AND GAMES
Potential energy is energy of position or place – where you are in the right place to do the job.
Kinetic energy is energy of motion – you are now in action.
QUESTIONS FOR YOU:
Where can you clearly observe potential energy & kinetic energy...
… at the line of scrimmage?
… when the quarterback is going to pass the ball?
... when the kicker is going for a point after touchdown?
WHAT IS COLLISION?
Collision is much more than an auto accident.
Collision happens whenever any two objects touch each other –
whether it's a light touch or a hard touch. It ranges from:
elastic collision (with a lot of 'give')
inelastic (or non-elastic) collision (OUCH!, this has NO 'give'),
on a scale from 1 to 10 (see below).
Egg Toss (or Water Balloon) Contest: This is one example.
If you throw the egg gently at close range,
the catcher experiences elastic collision, say a 1.
On the other hand, if you throw the egg hard and at a distance,
the egg might break (SPLAT!!) on the catcher;
call this a 10 (completely non-elastic).
If, however, the catcher moves their hands back
(we call this 'giving with' the egg, or it has some 'give'),
then it increases the distance and time –
and may result in the egg not being broken.
This moves it back toward the elastic range,
and the collision might be a 7.
WHAT DO WATER BALLOONS AND EGGS
HAVE TO DO WITH FOOTBALL?
Playing a water balloon or egg toss game could be a good way to learn how to minimize injuries. First of all, minimizing injury is the reason that helmets and padding are worn. More than equipment is involved in protecting against injury, though.
Knowing how to fall is another way. If a player falls hard on the ground, injury may result. However, if he can roll – thereby extending the time and distance of impact – he is more likely to emerge unharmed.
You know the boxing term,
roll with the punches?
That's about collision!
You could think of collision as
being on a scale from 1 to 10:
elastic 1 2 3 4 5 6 7 8 9 10 nonelastic
My scale may help you get the idea of collision.
Sports and games are the gateway to science, and YOU hold the key!
is just one of endless ways to gain an understanding of physics and geometry. I hope this leaflet introduces you to seeing things you never saw before – or wondered about but just didn't know where to start.
Physics and geometry come into play in every activity and event going on around us.
Knowing how things work can add to your performance and to your fun. So give it a try. How?
