This editor-recommended interactive tutorial from The Physics Classroom introduces the concept of acceleration of gravity. It is the second of a five-part segment that explains free fall motion and how free fall is represented by graphs. Students will be engaged by the simple language, informative graphics, and interactive widgets.
Editor's Note:This tutorial was developed for high school physics, but also serves well as content support for K-8 teachers. Don't miss the Gravitational Fields widget, which calculates the value of "g" at different locations on Earth. Why is the gravitational pull a little greater in Cincinnati than in Denver?

4. The Physical Setting
4B. The Earth
6-8: 4B/M3. Everything on or anywhere near the earth is pulled toward the earth's center by gravitational force.
6-8: 4F/M3a. An unbalanced force acting on an object changes its speed or direction of motion, or both.
9-12: 4F/H1. The change in motion (direction or speed) of an object is proportional to the applied force and inversely proportional to the mass.
4G. Forces of Nature
9-12: 4G/H1. Gravitational force is an attraction between masses. The strength of the force is proportional to the masses and weakens rapidly with increasing distance between them.
9. The Mathematical World
9B. Symbolic Relationships
9-12: 9B/H5. When a relationship is represented in symbols, numbers can be substituted for all but one of the symbols and the possible value of the remaining symbol computed. Sometimes the relationship may be satisfied by one value, sometimes by more than one, and sometimes not at all.
