Collisions in One Dimension: Linear Momentum & Collisions
Equal & Unequal Mass Air Track
PIRA Class: 1N30.33

Purpose
Observe equal & unequal mass collisions between carts on an air track.

Description
A small cart hits a big one elastically.
Collide carts on an air track & note the changes in velocities of the respective carts.
1. Set up track with air supply.
2. Level track & wipe off any dust.
3. Place carts on track with weights distributed evenly on carts' sides.
4. Give the carts a gentle push so as to collide them at the center of the track.
5. Transfer some of the masses from one cart to the other for unequal mass collisions.
NOTE: Use "velcro ends" on carts for inelastic collisions
VARIATIONS:
A. Launch the larger cart and smaller cart so that after the collision both carts hit the ends simultaneously. The carts will again collide at the original collision position.
B. Vary initial velocities of carts by colliding a still cart with a moving cart.
C. Vary initial velocities of carts by initially sending the carts down the track in the same direction.
D. Simulate the Doubleball drop (Basketball & tennis ball drop)
