Dynamics Cart Accessory Track Set 012-05035E
Displace the two carts on the left away from the cart on the right and release and observe the mode of
oscillation.
Displace the middle cart and release and observe the mode of oscillation.
Experiment 17: Multiple Elastic Collisions
(For the ME-9459 system)
Use two Collision Carts and one Dynamics Cart. Try this experiment with carts of the same mass and
then with carts of different masses. Set the three carts on the track with the Dynamics Cart on the right
end with its magnetic bumper oriented toward the Collision Carts. Push the left Collision Cart into the
middle cart, which in turn will collide with the right cart. Note the resulting final velocities of each cart.
Experiment 18: Multiple Inelastic Collisions
(For the ME-9459 system)
Use two Collision Carts and one Dynamics Cart with its magnets removed. Alternatively, two Dynamics
Carts and one Collision Cart may be used. Try this experiment with carts of the same
mass and then with carts of different masses. Set the three carts on the track with the carts arranged so
that the Velcro bumpers will collide without magnets to push them apart. Push the left cart into the
middle cart, which in turn will collide with the right cart. The carts will all stick together. Note the
resulting final velocity of the carts.
Experiment 19: Rocket Staging
Use three or more Dynamics Carts (with plungers) to simulate a rocket expelling fuel. Push the plungers
in on each cart and attach the carts together in a line on the 7.5' track. Tape can be used to lightly attach
the carts to each other or Velcro can be added to the bumpers. Position the carts at one end of the track.
The lead cart represents the rocket and the rest of the carts are fuel. Use a meter stick to release the
plungers in succession by striking the plunger-release of each cart, beginning with the last fuel cart
(furthest from the rocket cart). As each plunger is released, each cart will separate from the rest, one at a
time. Note the final speed of the rocket cart compared to its speed when all the fuel is dumped at once.
Experiment 20: Longitudinal Wave
Use six or more Collision Carts on the 7.5 foot track with the adjustable end stops installed at the ends of
the track with the magnetic side of the end stops toward the center of the track. Start a longitudinal pulse
by displacing one of the carts. The carts will rebound off each other and the end stops. Oscillate the end
cart to keep a longitudinal wave going down the track.
