Photogate

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 Choose

Our 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 Are

The 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.
