While getting ready to hit a jump, there are a
number of things to keep in mind. One is the speed
   in which you hit the jump at. Since you will be
converting potential energy into kinetic energy, the
 amount of kinetic energy you have will determine
   how fast you'll hit the jump. Remember that the
   ramp will slow you down some.If you feel that
 you'regoing to hit the jump too fast, lowering your
  kinetic energy is simple-just put more friction on
   yourself. More friction can be caused by simply
  carving your board into the ground harder, which
                        will slow you down.

         Approaching the Jump

   Once you've gone up the jump, it's up to you to
   safely soar through the air so that you can land
   correctly, or at all. There is physics involved in
     doing tricks in the air, or simply just soaring.
     Gravity plays a big role in this, because once
    you're in the air, by the laws of gravity, you're
  going to come back down eventually.If you're
 more of a pro and plan to do flips and/or spins, it's
   important to consider your angular acceleration
                                 as well.

             Jumping the Jump

   Landing a snowboard jump is not an easy task.
 This is why the physics of landing is so important
   in the success of the rider. Since, as previously
mentioned, once you're in the air, you have to come
   back down, its important to stay balanced. This
   means it's important to stay upright at all times,
or if you're doing tricks to make sure your board is
parallel to your landing when it's time to land. This
ensures a smooth as possible landing. However,
always be prepared to land hard and therefore have
   your speed decreased. Prepare your landing by
      bending your knees and not being too stiff.
