A skate can roll like a 'ball, bearing' in mind that it will only roll in one dimension whilst a ball will roll in two !

Well, theres not enough information here. \nYou have to take into consideration, the angle of the ramp, the weight of the ball, whether the ball is pushed or released, the material which the ramp and ball is made of (their frictional properties)

well there's no such thing as a pro skateboard...but what do you mean by what kind of bearings...brand or abec?  if you're talking about abec then most pro street skaters use abec-5 bearings, while vert skaters like a bit more speed. so theyll use abec-7.  abec-3,5, and 7 are the most common.  the higher the number the faster and longer the bearing will make the wheel spin, but they need cleaned often and dont last as long.  as for the brand, they will skate bearings from whichever company gives them sponsorship.\n\nmost pros do not skate element bearings, they skate whoever they're sponsored by.

In case you don't know much about curling shoes, one shoe has a thick, flat plastic coating on the bottom, and the other one has a rubber bottom. The rubber bottom shoe doesn't slide, but the one with the plastic coating (called the slider) does. I have actually used my curling shoes on a skating rink and it is ok. It does get a little tiresome though, since you stand mostly on one foot (the slider) when you glide.

This is your lucky day!  I used to teach skating lessons back when people skated on 4 wheelers.  I'm assuming they still come equipped with a rubber toe stop on the front.  The first thing to learn is to drag the toe stop behind you while skating forward and slowly bring yourself to a stop.  Once you've mastered this, you'll realize how geeky it is.\n\nThe next thing to do is to learn how to skate backwards.  Starting at a standstill with your toes pointed together, force your feet apart in an outwards motion and then bring them back together again.  Sort of like doing an hourglass over and over.  This will get you going in a backwards motion.  To stop, simply lean forward on both toe stops.  It's fun when you're going fast.\n\nAs you become better, you'll learn how to stop without the toe stops when you're skating forward.  One way is to drag one foot behind the other in a sort of t-shape.  So instead of dragging the toe stop, you're dragging the inner front and rear wheel of the skate that's stopping you.\n\nEventually, you'll learn how to stop much the way skiers do, by turning both skates sideways and catching the inner edge of the right foot and the outer edge of the left foot at the same time.

Well . . . first, get a really good handheld video camera. Find a few places to skate Then the best way is to tape your friends naturally. You get problems if you start controlling moves. You'll be amazed of the stuff you get when you let your skating flow. It may take hours of filming. When you get enough of what you want, use a computer program, like MovieMaker, and put it all together. Be careful. :)

i assume you're talking about baseball; but all it is is that there is a spinning wheel incased in a large metal structure. there is a whole where a baseball is placed. depending on how fast you want the pitch to go you can adjust the speed the wheel turns. once the ball goes down the chute and lands on the wheel, the wheel accelerates the ball forward, simulating a pitch

Skate shoes have wheels. You can't miss them. They're the round things.

Well first a cannon ball is basically a hard ball, for that try to hit it just in the middle, and put some direction to where you want your ball to go.\n\nThen the curling, you can apply it by hitting the ball with the interior part of the shoe creating a spin and giving some direction, as more to the edge you hit it, the hit would go perfect.\n\nIf you don't know some terms ill help you with that too.\n\nInterior Part: The part that faces the other shoe, this part is usually used to give short passes, because you can calculate the precision and the strenght\n\nSpin: hitting the ball so it makes a curve, it depends to where do you want to shoot, and which leg you are using.\n\nCannon Ball: Very hard ball, that usually doesn't have any effect(curling ball, loose-speed ball, backward ball, and some others) this is mostly use for hits that want to have a fixed direction.\n\nCurled Ball: Is referred to the ball that has some effect  that when you kick it, doesn't finish in the same side the ball is suppose to go. The ball has a shape of a curve in the air.

You want something that fits good and feel comfortable.  I wouldnt suggest going out and getting the most expensive top of the line skate, but don't buy the cheapest either! In-line skates come with wheel bearings that have a number rateing associated with them, if you have ever ice skated in your life and are pretty good then you can go with a APEC 5 bearing and do well, if you are a true all out beginner, stick with an APEC 3 bearing.  The lower the number the less speed you can generate while skating.  You want something with plenty of ankle suport too, you might not get the prettiest pair on the rack, but if you are serious about skating on the regular you dont need to worry about a fashion show do you?  Also get something with a REAR break on it, stay away from hockey skate replicas!  Try going to a sporting goods store, stay away from Wal*mart and stores like that.  Usually the people in those department are extremely helpful.  I hope I shed a little light on the subject for you!  Good luck and have fun skating.\n\nOH PS - Get a helmet, again you arent in a fashion show!  Protect your noggin!  If you are a real beginner you WILL fall!

First answer these questions: how well do you skate(especially backwards)? How well do you stickhandle? pass? Is your wrist shot accurate? do you have a hard slapshot? How is your endurance? Are you disciplined defensively? Do you need to have assists and goals to feel like you did something to help your team win? To help:\n\nGoalie -- You must be mentally tough. Can you forget about a goal you gave up and continue to concentrate. Can you skate well backwards and laterally?\n\nDefense -- Do you skate well backwards? Can you think in terms of who scored AGAINST you while you were on the ice? Do you have a hard, low slapshot?\n\nWing -- Can you go into the corners and come out with the puck? Do you have an accurate wrist shot? \n\nCenter -- Do you have skills with the puck (stickhandling and passing)? Do you have good peripheral vision? You will have to skate hard to be near the puck at all times -- are you up to it?\n\nHope this helps!

find the right size skates, lace them up properly. the skate blade should feel like an extension of your foot. no ankle bending if you lace em up right. hope you have good balance! keep practicing, soon you will skate like the wind.

The force of friction always opposes the motion.  \n\nWhen a force is applied to a ball or wheel, it will start rolling, provided there is a resistive force preventing the wheel from simply sliding along the other surface. The force may be a torque applied to the axle of the wheel or a linear push or pull on the wheel. The resistance of static friction causes the rolling motion. If the wheel or tire has treads and the other surface is soft, then those treads provide extra friction known as traction.\n\nNote that the friction required to start rolling motion is not rolling friction, which is defined as the friction slowing down rolling motion.\n\nAccording to the law of conservation of energy, no energy should be lost due to friction. The kinetic energy lost is transformed primarily into heat and/or motion of other objects and fluids. An airplane will heat and accelerate the air as it passes. A submarine will do the same to the water. In some cases, the "other object" to be accelerated may be the Earth. A sliding hockey puck will come to rest due to friction both by changing its energy into heat and accelerating the Earth in its direction of travel (by an immeasurable amount)

good question. The first thing I would advise you to do is not watch how other skaters skate. A lot of these skaters don't skate correctly. Check with your rink to see if they have a learn to skate for hockey or learn to play hockey. You didn't Say how old you are so if you are in youth hockey, your coach should be showing you the proper stride skating forwards and backwards. One of the answers you got from someone on this question was the push on the back of your skate. That is wrong for hockey skates, but right for in line skates. The push on hockey skates is on the front part of your blade. Remember, your blade has a rocker on the front and back of your blade. Your weight is forward when skating, not backwards. Backwards, you fall down. If you are older, out of high school. then check your rink to see if they have any adult classes for skating skills. It's good to learn the proper way to skate from someone who is certified to teach. Even figure skating teachers can show you the correct way to skate on hockey skates. Good luck.

DO NOT EVER USE ONE of those peices of crap. They do a really really bad job. I've even seen buddies who have tried them and their skate got stuck in kind of crooked and it totally wrecked their blade.I've also seen where the machine wouldn't stop and it ground the blade right down to almost nothing. If you really need to get an edge on your blade and you can't have them done, carry an edging stone in your bag. You can buy them at every hockey supply store and you just run them along the side of your blade to give you a bit more of an edge on them. DON'T EVER use one of those stupid machines. Unless you can afford to buy a new pair of skates the next day.
