Description
Rotational motion is experimentally investigated using a modified fidget spinner and smartphone. The experimental results are described by a didactic model based on the Newton’s second law for the rotational motion, considering the resulting resistive torque acting on the system. We analyse the physics concepts that are involved in the experimental activity, such as angular velocity and moment of inertia. We show that it is possible to transform a well-known popular toy into an opportunity to teach/learn physics concepts, by performing easy and valuable physics experiments in classroom at undergraduate and first-year university laboratory.
