ice skater effect

fifteen  minutes including assembly time  two
 two pound 9-kg  hand weights a swivel chair. Have you  seen an ice skater spin bringing  her hands is and out to increase her motion This is what you're  doing  without  ice skates as you  bring your  hands and arms and weights closer to your body you move mass closer to the vertical axis of your rotation  you can use this information to speed up or slow  your spin .in swivel chair  your hands and start to turn  chest level and your arms to the side with your  elbow slingtly  bent  now bend your elbow more and  pull  the weights in to your chest together  continue this motion in and out with the weights to  see how affects your spin .The weights and  your arm action don't  get then start motion .  spotting  is sometime dancers team to do when they  spin to keep from  getting dizzy and  as you spin look for that spot turning you  hand quickly  to get to it.  The tighter  smaller motion with the  elbow bent  all the  way as  you bring  the weights to chest should  increase your spin . in spin you reach  a balance between  inertia no motion and  in  which motion shown  you spin faster when you pull your hand s and the weight the in because  you pull  mass toward the center of the spin its  vertical axis. what part of the motion shows you down the most how long can you keep spinning  using the weight  does the weights of weights make different  does the  weight  of the person  doing the experiment   change the  outcome. That weird adana.
