Impulse Comparison for Elastic and Inelastic Collisions
Keith Michaelsen, Southington High School, Southington, CT, contacted us to discuss ways to show students that the impulse delivered during an elastic collision is twice the impulse delivered by an inelastic collision. This is a counter-intuitive concept, and performing an experiment to observe this can be a challenge. Here’s how we would do it.

Cool Tools: Vail Ski and Snowboard Academy and Video Analysis in Logger Pro
The Vail Ski and Snowboard Academy uses Vernier tools to help their student athletes analyze their motion on the race course and in the terrain park. Miles McGeehan, physics instructor, has developed a course titled Ski Physics. Each week, students address a different concept in Newtonian physics.

Studying the Efficiency of Solar Panels
Nick Glembotski, an engineering student at San Diego State, recently used our Current Sensor, Voltage Probe, and Surface Temperature Sensor to investigate whether the efficiency of solar panels can be improved by cooling the panels by spraying them with a mist.
Rotary Motion Motor Kit
This kit includes a small electric motor with pulley, rubber band belt, motor clip, and mounting screw. The motor can be attached to the Rotary Motion Sensor, and be used as an analog tachometer, or generator. You can also perform experiments that investigate motor efficiency in different conditions.
Rotational Motion Accessory Kit
This accessory kit is used with the Rotary Motion Sensor to study the motion of a physical pendulum; the rotational inertia of disks, rings, and point masses; and the conservation angular momentum.
Color Mixer Kit for Vernier Track
Experiments in additive and subtractive color mixing can be easily and conveniently carried out using the Vernier Color Mixer Kit. The Color Mixer Kit consists of a three-color LED illuminator with power supply, a lens, and a double-sided screen.
Optical Fiber Holders for Spectrum Tube Power Supplies
The Fiber Holders for the Spectrum Tube Power Supplies securely holds an optical fiber in the proper position to carry light from the discharge tube to the spectrometer. Compatible with both Ocean Optics fibers and Vernier SpectroVis series fibers. The position of the fiber can be adjusted to optimize the light intensity.
Spectrum Tube Carousel Power Supply
The Spectrum Tube Carousel Power Supply features the same ultra-safe, patent-pending design of the Single version, but holds six gas spectrum tubes simultaneously. You can quickly switch from one gas to another without handling the tubes.
The power supply allows your students to view spectral lines using any of our spectrometers. Unlike other designs, there is no exposed high voltage. The gas tubes are permanently enclosed in plastic carries that protect the tubes from breakage. There are no through-the-glass electrodes, so the tubes last far longer than older designs.
Spectrum tubes sold separately.
Spectrum Tube Single Power Supply
With ultra-safe design, this spectrum tube power supply will provide a simple means of viewing gas discharge spectral lines with any of our spectrometers. Unlike other designs, this system has no exposed high voltage. The gas tubes are permanently enclosed in plastic carriers that protect the tubes from breakage. There are no through-the-glass electrodes, so the tubes last far longer than older designs. The Power Supply will energize one tube at a time, and includes storage space for an additional six tubes. All tubes sold separately.

High Voltage Electrostatics Kit
The High Voltage Electrostatics Kit is an accessory for the Vernier Charge Sensor. Use it with a Faraday pail and the Charge Sensor to investigate the distribution of charge on a sphere, transfer the charge on contact between two spheres and charging by induction. The kit includes an electrostatics voltage source (output 750, 1500, 3000, 6000 VDC) and two conducting spheres. Extremely low output current makes this device safe for classroom use.
