Picket Fence

The Pulley Bracket attaches an Ultra Pulley to the end of a Vernier Dynamics Cart and Track System.

Using Go Direct Photogate, students are able to easily and accurately measure velocity and acceleration to study the movement of an object in free fall, rolling objects, collisions, and pendulums, without needing to know anything about the geometry of the object. Go Direct Photogate also includes a single laser gate for use with objects passing outside of the arms of the sensor. Using the laser gate requires a visible-light pen laser (not included). Go Direct Photogate can be used in a variety of experiments: Measuring acceleration of a cart on an incline using a cart picket fence Measuring the angular motion of a wheel as it is turning Investigating Newton’s second law using a half-Atwood machine to measure acceleration Determining the time an object passes one or more gates Wired or Wireless—The Flexibility to ChooseOur Go Direct sensors connect directly to your mobile device, Chromebook™, or computer using our free Graphical Analysis™ 4 app—no additional equipment or software purchases are necessary. Go Direct sensors can be used wired via USB or wirelessly via Bluetooth® wireless technology, allowing you to choose the solution best for your classroom or laboratory. Rechargeable Battery—Ready When You AreThe robust rechargeable battery offers long battery life and provides always-ready operation when using the sensor wirelessly. Monitor battery life directly from our free Graphical Analysis™ 4 app or LabQuest 2 App. Should the battery run low, simply connect the sensor to the charging cable and keep on collecting—no interruptions or inconvenience to you or your students. Specifications Infrared source: Peak at 880 nm Gate width: 77.5 mm Internal gate separation: 20 mm Distance from internal gates to bottom of photogate arms: ~10 mm Distance from internal gates to sides of photogate arms: ~5 mm Gate LED indicators: Off for unblocked gate, on for blocked gate Battery: 300 mAh Li-Poly Rechargeable Battery life (single full charge): ~10 hours continuous data collection Battery life (long term): ~300 full charge cycles (several years depending on usage) Connections Wireless: Bluetooth Wired: USB

For use with Vernier digital sensors. Most of Vernier sensors have cables that are 1.5 m long. There are times, however, that you may wish to have a longer cable. The Digital Sensor Extension Cable can be used with any Vernier sensor that connects to a digital channel of one of our interfaces. The port will be labeled DIG1 or DIG2. Each cable is 2 meters in length.

This Class 2 (<1 mW) laser pointer can be used with the Vernier Photogate to produce a gate that is wider than the normal 7.5 cm spacing, making it possible to measure the speed of an automobile or of a person running. The laser case is made of aluminum, and it uses two AAA batteries (included). The wavelength of the light is 650 nm. A momentary switch (normally off) controls the laser beam.

Add an Ultra Pulley to your Photogate to monitor motion as a string passes over the pulley, or as the pulley rolls along a table.   You can also connect the ultra pulley to our track with the Pulley Bracket.

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.

Photogates allow for extremely accurate timing of events within physics experiments, for studying free fall, air track collisions, pendulum periods, the speed of a rolling object, among other things. The Vernier Photogate includes an accessory rod for mounting to a ring stand. The gate has an input port so multiple gates can be connected in a daisy-chain configuration with up to four gates going to a single interface channel. The laser gate mode requires the addition of a common pen laser, which is directed into the laser port. The laser may be some distance from the gate, so that you can measure the speed of larger objects such as a rocket, model car, or even a real automobile. User manual

Replacement cable for connecting a Vernier Photogate to a Vernier interface.

Dieses leichte Stativ ist eine perfekte Stütze für den LASER, der einen Aussendurchmesser von 1,1 cm hat. Der Ständer verfügt über ausklappbare Beine und einen Clip, der an der verstellbaren Kugel befestigt ist. Ein Sockelkopf befestigt den Laser sicher in Position. Mit dieser Montage können Sie den Laser präzise auf die Fotogate richten. Ein in eines der Stativbeine integrierter Gurt ermöglicht die Befestigung des Lasers an Objekten wie Ringständern und Geländern.
