This is a demonstration and explanation of free fall. It demonstrates that in the absence of air resistance, an elephant and feather strike the ground at the same time. It includes some true/false statements with which you can test your understanding, as well as links to further resources, including relevant sections from other Physics Classroom tutorials. It also has a link to a demonstration of the same scenario, but with air resistance. (See Newton’s Laws: Elephant and Feather - Air Resistance.)
