1N30.30 Collisions in One Dimension: Inelastic and Elastic Collisions on
an Air Track
Please click your browser's "back" icon to return to the Demo Master List
Instructions / Notes:
Two air track gliders have either a spring on 1 end
or a velcro pad.
For elastic collisions move one of the double spring gliders - using a slow but steady motion - towards
the second air track double spring glider, which should bed place in the center of the track.
For inelastic collisions repeat the above procedure, but use the two gliders with velcro pads - make sure the velcro
surfaces face each other.
The paired velcro carts should each have different colored writing, (i.e.
1 red lettering against 1 blue lettering).
Gliders show an equal mass collision of 1M vs. 1M - or -by adding 2 round weights to one of the gliders to show 2M vs. 1M.
At slow speeds this demonstration will function beautifully.
Demo Staff: Make sure the PASCO air track is leveled before before leaving the class.
Demo Staff: Notice the proper set-up for classroom use in the photo below.
