External Forces and the Third Law

To investigate Newton's Third Law, the forces are examined that are exerted on the two sensors by a connecting string. Also, the external force exerted by hand on an elastic cord is compared to the internal forces created by the tension in the string.

Featured Equipment

Comprehensive 850 Mechanics Bundle

This bundle includes all the equipment and sensors needed to perform the experiments in the Comprehensive 850 Mechanics System Experiment Manual.

High-Resolution Force Sensor

PASPORT High Resolution Force Sensor

The PASPORT High Resolution Force Sensor is designed to make very high resolution measurements of pulling and pushing forces.

Motion Sensor

PASPORT Motion Sensor

The PASPORT Motion Sensor accurately measures the position, velocity, and acceleration of a target. It can be used to track the motion of balls, carts, people, and more.

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.
