Go Direct® Sensor Cart

The Go Direct Sensor Cart features built-in, wireless sensors for one-dimensional dynamics and kinematics experiments. It directly connects wirelessly via Bluetooth® wireless technology to your platform.

SKU: N/A Categories: , ,



With 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 investigations to be conducted on or off the track.

Go Direct Sensor Cart can be used for hands-on kinematics and dynamics demonstrations but can also be used as an individual sensor. Hang a mass and spring from the force sensor to study simple harmonic motion, or attach the cart to a turntable to study centripetal acceleration.

Each full-featured dynamics cart includes

  • Encoder wheel to report position
  • 3-axis accelerometer to measure independent acceleration
  • ±50 N force sensor to measure push and pulls
  • Mass trays for changing total mass
  • Plunger for collision and impulse studies
  • Low friction wheels for uniform motion

The Go Direct Sensor Cart can be used in a variety of experiments:

  • Collect position, velocity, and acceleration data as a cart rolls freely up and down an incline.
  • Observe collisions between two carts, test for the conservation of momentum, or measure energy changes during different types of collisions.
  • Investigate the relationship between force, mass, and acceleration.
  • Examine the energies involved in simple harmonic motion.
  • Measure a cart’s momentum change and compare it to the impulse it receives.

Go Direct Sensor Cart connects directly to your mobile device, Chromebook, or computer using our free Graphical Analysis 4 app.

Go Direct Sensor Cart is also available as a part of the Dynamics Cart and Track System with Go Direct Sensor Cart.
