Conservation of mechanical energy during free fall  

Using these models students can investigate changes in motion (distance covered, velocity, and acceleration) and mechanical energy (kinetic and potential) of an object under free fall. Using a block-based coding interface, NetTango, students can build a model of an object under free fall.

A lesson built around these models has been published on the CT-STEM website. It can be accessed and administered using the following link:
