The kit allows the user to upgrade one existing cart to a Motion Encoder Cart and includes the Motion Encoder Receiver (MEC-BTD) and a Motion Encoder Long Track Strip (METS-LONG). One-time assembly requires removing a cart end cap, installing a transmitter unit underneath the cart, and installing a replacement end cap. Compatible with Vernier Dynamics Cart and Track System only. The Motion Encoder Long Track Strip can be trimmed to fit the 1.2 m dynamics track.

This book contains over 30 guided-inquiry-based investigations for physics students to explore and analyze key physics concepts included in NGSS. Description Physics Explorations and Projects is a collection of laboratory investigations aligned to the Next Generation Science Standards (NGSS). Most included investigations set up a situation for students to explore and analyze with some guidance from the instructor—a guided-inquiry format that is very different from traditional laboratory experiments that provide step-by-step instructions. The activities are editable and appropriate for high school students from 9th grade to AP Physics. Sample results are included with the extensive instructor information. Due to the nature of these activities, minimal instruction is provided for software use and data analysis. Instructor experience with Vernier sensors and software is recommended.

Use the Diffraction Apparatus to map light intensity vs. position for various slit geometries. The Diffraction Apparatus let students create, view, and measure diffraction and interference patterns. The included Red Diffraction Laser provides a clean monochromatic light source. Slits are made by depositing metal film on glass, creating extraordinarily clean slits with fully opaque blocking areas. These high-precision slits cast clean diffraction and interference patterns, ideal for quantitative matching of intensity vs. position predictions. The Linear Position Sensor and High Sensitivity Light Sensor completes the Diffraction Apparatus. In order to provide excellent spatial resolution, a selectable entrance aperture restricts the width of the pattern viewed by the High Sensitivity Light Sensor. The light sensor has three ranges, allowing the study of fine details or gross features of patterns. To measure position, the light sensor is mounted on a novel Linear Position Sensor. This position sensor uses a precision optical encoder to measure translation with better than 50 micron resolution. Since it is optically based, without gears or racks, it has zero backlash. Data collection is performed by choosing a slit, directing the laser through the slit, and choosing an entrance aperture for the light sensor. Both the light sensor and position sensor connect to your interface. The light sensor is moved by hand over a 150 mm distance, tracing out the diffraction pattern. The Diffraction Apparatus requires a Combination 1.2 m Track/Optics Bench individually or part of the Dynamics Cart and Track System. An optional Green Diffraction Laser is also available, so that the effect of wavelength on the pattern can be measured.

Questa nuova rotaia, in alluminio anodizzato e serigrafa- ta in cm e mm, è stata ridisegnata per aumentare le prestazioni del modello precedente; è sempre disponibile in due lunghezze da 1,2 m e da 2,2 m e dispone adesso di una ulteriore stringa a barre per l’utilizzo per il nuovo sistema encoder digitale; la struttura è molto rigida ed è scongiurato il pericolo delle flessioni durante l’uso. Ė possibile raddoppiare la lunghezza tramite un giunto di connessione ed una rotaia addizionale. I carrelli dinamici, di nuovo disegno, sono lo strumento perfetto per gli esperimenti di cinematica e dinamica; sono compatibili con i sensori di forza e di accelerazione, e possono essere montati sui carrelli stessi; sono facil- mente zavorrabili con quattro pesetti da montare lateralmen- te ed facile cambiare la configurazione velcro/magneti; il montaggio dei sensori è una operazione di grande sem- plicità. Fate andare su e giù il carrello per la Rotaia per studiarne il moto o usate due carrelli per analizzare la conservazione della quantità di moto in un urto. Grazie ad un attrito bassissimo con la rotaia, ottenuto tramite speciali cuscinetti a sfera, questi carrelli di eccezionale qualità permettono di ottenere dati di laboratorio privi di rumore e facilissimi da analizzare. Le estremità smonta- bili possono essere dotate di respingenti magnetici o di adesivi in velcro, rendendo i carrelli estremamente versa- tili. Uno dei due carrelli viene fornito con un respingente meccanico a molla che permette di effettuare esperimenti per lo studio di collisioni o “esplosioni” di carrelli. In questa rotaia è possibile montare una serie di acces- sori che permettono di effettuare esperimenti di base ed avanzati di ottica geometrica (vedere pagine seguenti). I sistemi combinati V-VDS (da 1,2 m) e V-VDSL (2,2 m) comprendono: Rotaia da 1,2 m o da 2,2 m, dotata di serigrafia con barre, utilizzabile anche per esperimenti di ottica e con possibilità di espansione con rilevamento ad encoder. Carrello standard con estremità rimovibili magnetiche e/o adesive con velcro, Carrello con respingente meccanico con estremità rimovibili magnetiche e/o adesive con velcro, Serie di 4 masse esagonali da 125 g, Coppia di piedini regolabili in altezza, Blocchi di fine corsa regolabili, Un supporto per sensore di posizione 2 supporti per fototraguardi, Supporti per sensori e fotocellule Fine corsa regolabile

Replacement axles and wheels for the standard cart and plunger cart. Sold in pairs of two axles, each with two wheels permanently attached. Purchase this part to replace damaged wheels, axles, or bearings.

The Motion Detector is used to measure position, velocity, and acceleration of moving objects. It uses ultrasound to measure the position of carts, balls, people, and other objects. Measure objects as close as 15 cm and as far away as 6 m. Sensitivity switch reduces noise and produces higher quality data for studying dynamics carts on tracks. Attaches easily to the Vernier Dynamics System. Pivoting head allows for flexibility in the experiment setup. User manual

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. The intensity of the red, blue and green LEDs can be smoothly controlled from the light source. For more optics experiments with the Dynamics Cart and Track System, see the Optics Expansion Kit (OEK). The Color Mixer Kit requires a Vernier Track to serve as an optics bench. The Vernier Track is included with a Vernier Dynamics Cart and Track System. User manual
