Gravitational Field Strength

Mr. Anderson explains gravitational field strength, a measure of gravitational force on an object in a field. He discusses how the moon's orbit around Earth is influenced by this field and explores factors affecting gravitational field strength, such as mass and distance. The video covers the formula for calculating gravitational field strength, developed by Newton, and provides example problems involving a baseball and Earth. It concludes with a discussion on variations in Earth's gravitational field strength due to geological differences and latitude.
