How to demonstrate Newton's law of inertia

This short video clip shows seven demonstrations of Isaac Newton’s first law of motion– the law of inertia. Newton’s law of inertia states that objects moving at constant velocity will continue moving at constant velocity, unless acted upon by an outside unbalanced force. Six of these demonstrations (excluding number six) are from Tik Liem’s book Invitations to Science Inquiry.

So, if you're a teacher, have your science students try out some of these experiments to educate them on how Newton's law of inertia works.
