Physics 2215 Laboratory Equipment List

2215 Lab 7: Ballistic Pendulum

Dynamics cart with masses and force probe attached

Equipment List:

  1. Lab Pro Interface
  2. Ballistic Pendulum Setup:
    • Vernier Rotary Motion Sensor in DIG1
    • Rotary Motion Sensor Wheel connected with the largest pulley the furthest from the sensor.
    • Ballistic Pendulum Attachmentwith a long screw in it attached to the wheel.
    • 90 cm rod
    • Mini-Launcher attached with the ball image level with the ball holder in the pendulum
    • Table Clamp-Large
  3. Cocking Rod
  4. 1 Pair Ball Steel-16mm
  5. 2 Pairs or Safety Goggles
  6. Projectile Stop
  7. Carpenters Square
  8. 2 meter stick
  9. Carbon Paper
  10. A few sheets of Plain Paper

General class use:

  1. Large Balance
  2. Disinfecting Wipes. Also place another 1 or 2 containers around the room in a visible spot.
  3. Masking Tape

Notes and tests:

  1. The ballistic pendulum launcher should be set up to launch the projectile away from the nearest other setup.
  2. Make sure the gun is pushed back to be level with the metal framing and it is pointing straight.
  3. Make sure when fired the ball gets caught in the styrofoam. There are various slight adjustments that can be made to fix this. Ask your supervisor.
  4. Disinfect all Safety Goggles.
  5. Open the file "ballistic.cmbl" to test. When the ball is caught, the angle should go above 50 degrees.

Transition Notes: (Summer Only)

  1. Nothing remains from the previous lab. Take it all away.
  2. Sweepy sweepy.
The full table set up of the ballistic pendulum lab. The launcher and pendulum are on the left. The projectile stop and paper are on the right. The loose items are between with the 2 meter stick across the table with 0 near the pendulum and the other end near the bin.

This is what your table should look like once set up.

The side is determined by the which way makes the pendulum swing in the positive direction when the ball is launched.

Additional Images below:

The loose items.

The projectile stop on the right of the table with the carbon and regular paper to the left of it. The 200cm end of the 2 meter stick has about 10 cm off of the table.

Backstop for ballistic Pendulum should be placed as far away

from the pendulum as possible and aligned by shooting the ball.

The ball image on the end of the launcher is aligned

with the hold in the catching part of the pendulum.
