Pulley Bracket

Picket Fences have eight opaque bars spaced every 5 cm, silk-screened directly onto clear plastic. Drop the picket fence through a photogate to obtain records of position, velocity and acceleration vs time or to measure g.

This completely wireless system simplifies experiment setup and allows basic experiments to be conducted with or without the track. Description The Dynamics Cart and Track System with Go Direct Sensor Cart includes essential laboratory equipment for teaching dynamics and kinematics. Using our Go Direct Sensor Cart, students can explore force, position, velocity, and acceleration directly on their Bluetooth®-enabled device—no wires or additional equipment required. Each cart features built-in sensors to simplify experiment setup and allow experiments to be conducted on or off the track. Specifications Position resolution: 0.25 mm, reported by default at 1 mm steps Force range: ±50 N Accelerometer range: ±160 m/s2 Track length: 1.2 m Shipping costs standard version: The standard version 1.2m is sent as PostPac Economy bulky goods. The total shipping costs are CHF 31.00.   Shipping costs long version: The long track version 2.2m is shipped by freight forwarding. The costs for shipping amount to a total of CHF 74.00.

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.

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
