Swimming

When you are not in a streamline position in swimming, drag can occur. This is when you body is stopping the water from freely moving past your body. You may notice when you begin to sink while you are swimming that you slow down. This is because the lower part of your body is creating drag by stopping the water from quickly passing you legs.

So you do not drown. And whenever you swim remember God is there and will help you if you trust in him.

The Fairy Penguin (Eudyptula minor) is known to dive as deep as 60 feet and remain submerged for as long as 60 seconds. So they can swim at a rate of two feet per second. That's 60 feet down, and 60 feet returning to the surface, in one minute.

Body heat will be unable to warm the water around it, as fresh water will rush in to replace it. Were one wearing a waterproof suit, the body could heat the thin layer of water trapped inside the suit, but without such equipment the water will quickly bring on hypothermia.

Diving is how you start a race in swimming. (Except for backstroke) Swimmers stand on blocks and dive in the water when the race start. This is quite simple and takes a month to learn but years to master (Been diving 3 1/2 years now but still haven't mastered it)

25 meter long. Unless you are asking about time becuase if you are talking about time then it depends on what level you swim at. If you dogie paddle it will take much longer than if you used a freestyle stroke

I've just added swimming to my fitness routine. I am a relatively fit 40 year old who generally walks and rides a bike. After 3 non-sequential days of swimming, I timed a 100 yard freestyle swim (in a 25 yard pool) at 1:41.

It's hard to say what average is because it is so affected by age and endurance. A time of less than a minute is a sign that a young person has an efficient stroke. A time less than 52 seconds good time for high school swimmer, although a time of less than 48 seconds is needed for consideration as a High School All American. A time of less than 42 seconds is needed to reach the finals of the NCAA division one championships.

For a fitness swimmer, being able to consistently swim below 1:30 or 1:40 is very solid depending on one's age.

Hi I'm 15 year old and I'm a freshmen in high school. I just started swimming and I've been doing it for 2 months. My 100yd time is 1:15 in a 25yd pool. It all depends on your age and your fitness ability. So i say your time is pretty good for that age.

Assuming laps means two lengths (there and back in a lane):

1yd = 0.9144m

20yd = 18.288m

2 lengths = 36.576m

1km = 1000m

= 1000m / 36.576m

~= 27.34 laps

(just over 54 2/3 lengths)

I measured the one in Langhorne, PA and it was just shynof 25 yards.

Equipment for practices include: Practice suit and drag suit: These increase the drag (resistance) in the water so when you take them off to race you go alot faster Goggles: For the sole purpose of being able to see while your swimming Cap: Its really optional.. but for girls (and guys with long hair) it helps alot with keeping your hair out of the way. And there are really cute caps out there too! Fins: Used for kicking or swimming. Pull Buoy: A piece of foam that you put between your legs so you can pull and focus on your arms. This prevents kicking and also keeps legs afloat. A strap or tube can also be substituted for this Paddles: Increase pull against the water.. can either be traditional or fulcrom style paddles. These are usually used for pulling Snorkle: Sometimes used in pulling. This allows you to breathe while you swim without turning your head. Kick Board: A board that you use for kicking Equipment for Competition: Racing suit: Usually very tight and sometimes longer down the legs and arms. This provides the least amount of drag. Goggles Cap: Cuts out drag that hair has Warmups: Keep you muscles warm before and after races! and of course towels!

Such a shape has two components to its cross-section * A rectangle 11 metres long and 1.5 metres

and * a triangle 11 metres long and 0.5 metres high The square area of these is (11 x 1.5) + 1/2(11 x 0.5)

These work out as (16.5) + 1/2(5.5) = (16.5) + (2.75) = 19.25 Square Metres Now we can work on the width of the pool and get cubic metres 19.25 x 9 = 173.25 cubic metres. 1 cubic metre = 1,000 litres so 173.25 cubic metres = 173,250 litres.

It depends on how fast of a swimmer you are.

The answer is: The swimmer exerts a reaction force on the water.

Depends on the pool: usually 25 or 50 metres.

On Saturday morning Penny Palfrey went for a dip. A little over 40 hours later she emerged after setting the world record for the longest solo unassisted swim.

Her 68-mile trek across the Cayman Islands in nothing but a standard swimsuit and goggles bypassed packs of sharks, powerful currents, and unpredictable weather.

When she finished her swim last night at 11:11 P.M., her face and tongue were so swollen from the salt water she was unable to speak but she did manage to raise her arms in victory

Generally 25 yards but it can be 50 yard or 50 meters. 50 meter pools are used in the long course season of club swimming. High school swimming would be done in a 25 yard pool.

A suitable age to start swimming depends on the individual child; however, by 14 months, a child can learn to swim. Technically a child can learn to swim before then, but to be safe 14 months is recommended. This way, the child's verbal skills have been developed enough to express or show signs of being uncomfortable in the water.

Though its primary purpose is to stop water from going into a swimmer's ears, (and keeps hair fairly dry), it can help a swimmer to move faster. The cap has a tiny bit less friction with the water than hair does, and this can have a measurable effect on speed, especially at the competitive level.

To become classed as an Olympic pool, a swimming pool has to pass many specifications, just not in length. Width, depth, number of lanes, temperature and light levels are all taken into consideration.

Length, 51 metres, 50 metres between the touch pads.
Depth, 2 metres minimum,
Width, 25 metres,
Number of lanes, 8 +2 which are not used. Each lane must be 2.5 metres wide,
Temperature, 25-28 degrees Centigrade,
Light Level, 1500 Lux,
and lastly Volume, 2,500m3 minimum depending on depth.
Exactly 50 meters.

swiming is in the water and walking is on land
