Lesson Essential Questions:
Section 1: Explain how balanced and unbalanced forces are related to Newton's First Law of Motion.
Section 2: How does Newton's Second Law of Motion relate force, mass and acceleration?
Section 3: What is the Law of Universal Gravitation and how does it relate to air resistance and gravity?
Section 4: What is Newton's Third Law of Motion and how does it relate to momentum?
Section 5: How do forces how a satellite in place?
