A Moving Experience - Forces and Inertia

For Teachers 5th - 6th
Students consider the first part of Newton's First Law of Motion, the Law of Inertia of objects at rest, which states that every object remains at rest unless acted on by a force. They perform hands-on experiments which demonstrate this...
