When one stands up on a shortboard, is it supposed to sink?

It will if you are just sitting out in the water with it.  Shortboards are typically much lighter and thus require the speed of the wave to be the force that keeps both it and you riding on the surface of the water.  I use a shortboard most of the time but have a funshape for the little days here in SC.  Not exactly the mecca for surfing but you get consistent good days especially out at Folly Beach.

Your lungs will do the same job as the beach ball.  If you can relax and keep air in your lungs, you will float.  Try in shallow water, take a good breath, relax and lay back.  You will be fine.

when scuba diving the object is to put enough air into your bouancy compensator(bc) to remain neutrally bouant at a point. so you wont sink or float anymore. its basically balancing out the pressure above you with the pressure below you by surrounding yourself with air. so if taken to a certain depth maybe a decomposing body would release enuff air to remain neutrally bouant at a certain depth.

It depends.  Wood floats on water, as does ice.  Rocks sink.

You've got to remember to pull your knees up after you flip the board. Especially the one thats doing the flipping. Otherwise it's going to hit the board, or just go off to the side and to the ground. Jump, and when you do, lift up both legs and stay above the board while it flips, and then, ideally, it will finish it's rotation right under your feet and your feet will do what's called, "catch" the board.\nGood luck

A piece of iron has a density greater than water. Thus it will sink when the weight of the volume of water displaced by the piece of iron is less than the weight of the piece of iron. If iron is shaped, or used to make a ship,  the iron ship will float if the total volume of water displaced by the part of the ship in the water weighs more than the total weight of the iron used to make the iron ship. Thus, the upward force of buoyancy is greater than, or equal to,the downward force of gravity and the ship stays afloat.\n\nThis is called Archimedes's principle of buoyancy and it is fundamental to the design of all ships and heated air balloons.TWH

As already stated, a longboard is longer, wider, and thicker, making it more stable and easier to stand up on.\n\nA shortboard is NOT ALSO CALLED A FUNBOARD. Someone wrote that, and that's wrong.\n\nThere are boards called funboards. They are inbetween a shortboard and a longboard, with a different shape than a shortboard. These are good transitional boards, going from a longboard to a shortboard.\n\nA shortboard is smaller and less stable, making it harder to surf on but easier to maneuver.\n\nIf you are just learning, rent a longboard and take it out to a place with gentle waves to surf on.

just after you plane off.  this is when the bow levels off and your making less wake (pushing less water b/c the hull is higher out of the water)

ok when your doing one make sure your feet are in the right place,put your hand(fingertips) on the ground.your feet should be in the middle and on the tale.push down on the tail while jumping your fingertips will come off the ground.while in the air the firt on the tail slides back gives the board a little nudge so it flips.then quickly slide your foot back on the tale but right on the end.make sure both feet are on.then your board will drop down and you keep your balanece.that is a tip and you can think about something like if i land these ill get 1 million dollars or somethin on the lind.i hope this helps.oh yea yuo can practice in a pool,trampiline,or bed.thats what i did when i first learn how to do one now i can do them naturally.have a nice day

yes. the fact that he is still on the ground means that some force is holding him down which would be gravitational force. if there was no graviatational force then he would be 'floating' in the air as if in outer space.

Yes the scale will reflect the additional weight.\n\nThe downward force on the water is still an additional downward force which is measured by the scale.

Friction mainly affects surfing by making it possible for you to stand on the board. That's the only way I can think of off the top of my head.

STEP 1: Stand on the board with your rear foot placed on the tail and your front foot between the middle of your board and the front bolts.\nSTEP 2: Place the ball of your rear foot in the middle of the board so that when you push the tail down, the ball of your foot feels the pressure.\nSTEP 3: Place your front foot nearly straight across the board.\nSTEP 4: Practice pushing down as fast as you can with your back foot and putting all your weight on the tail. This is the initial motion of the trick.\nSTEP 5: Notice that the harder you push, the more your board wants to keep going up once the tail is on the ground. You will use that motion in the next step.\n\nSTEP 6: Strike the tail on the ground and jump off with your rear foot as you slide your front foot up the board (so your knee moves toward your chest).\n\nSTEP 7: Drag the side of your foot up the board as you are jumping. This will cause the board to come up with your jump. Once both feet are in the air, the board will seem to stick to them.\nSTEP 8: Come back down.\nTips & Warnings\n\nLearn this trick without rolling at first to get comfortable with the motions. Once you feel comfortable with the basics, you will be able to adapt to moving and going up or down things.\nThe hardest part is the timing of when to push down on the tail, when to jump, and how quickly to suck up your legs. The secret: It's all done at the same time. The faster you do it, the easier it becomes. Think about jumping off with one foot and sucking your legs up to your chest.\nSkateboarding is an inherently dangerous activity that can result in serious injury or death. We recommend that you seek proper training and equipment before attempting this activity.

I float in a fresh water pool, don't you?  My head is not above water, but if my lungs are full of air I do not sink.  If I empty my lungs then I will sink.  What is your question?

Mu,\n\ni.e. The question is incomplete, part of the ship will be above water, part below, depending on the exact nature of the ship and the position of the ladder a differing amount of steps will be visible when it is floating.

you will probably fall over.

Kick down on the tail, slide your front foot up and push down on the nose. Then level the board out. If I remember right anyway...
