Force and counterforce with Cobra SMARTsense

Principle

The students observe the effects of the principle of action and reaction and they find out that two connected dynamometers always indicate the same force, leading to the conclusion that when one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude on the first body in order to maintain the system at equilibrium.
