The patented ME-1240 ME-1241 multifunction wireless Smart Cart collects measurements both on and off a track and transmits data wirelessly via Bluetooth. It is the ultimate tool for studying kinematics, dynamics, Newton's laws, and more. Overview: The patented wireless Smart Cart is the ultimate tool for studying kinematics, dynamics, Newton's laws, and more. It has a durable ABS body and nearly frictionless wheels, like our high-quality PAS carts. We have now added built-in sensors to measure force, position, velocity, and acceleration. This multifunction Smart Cart collects measurements both on and off a track and transmits data wirelessly via Bluetooth. Essentially, it is a wireless dynamics cart integrating all the necessary sensors without requiring extra hardware. The Smart Cart is ideal for mechanics topics such as kinematics and dynamics. With their built-in load cells, two Smart Carts make it easy to demonstrate Newton's third law intuitively. In addition, the built-in force and acceleration sensors let students investigate Newton's second law in minutes. A physics laboratory on wheels, the Smart Cart puts the most advanced physics cart ever at your disposal without the restrictions of cables.
