Conservation Of Momentum

In this lab, students use a motion sensor and a dynamics system to demonstrate that linear momentum and kinetic energy are conserved in an elastic collision, and linear momentum is conserved but kinetic energy is not conserved in an inelastic collision.

Featured Equipment

Motion Sensor

Wireless Motion Sensor

The Wireless Motion Sensor uses ultrasound to measure the position, velocity, and acceleration of objects.

PAScar Cart Mass (set of 2)

These 250-gram masses fit in any Dynamics Cart (including the Smart Cart) or the Discover Friction Accessory.

Basic Smart Cart PAStrack System

The Basic Smart Cart/PAStrack system is made up of Wireless Smart Carts and a plastic track without the accessories package.

Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
