The science of crashing into stuff (Kinetic Energy)

Which is more dangerous, a softball, a football or a small RC plane? In this video I talk about the physics of kinetic energy and in the process of demonstrating how to calculate it, reveal just how safe a small, sub-250g foamboard FPV RC model can be when compared to the types of balls you might find in a typical park environment.

And for the benefit of the indexing algorithms: drone crash STEM STEAM
