CH 12.1: Gravity Objective: Students will be able to explain gravity and how it relates to free fall and projectile motion. ● Explain that gravitational force becomes stronger as the masses increase and rapidly becomes weaker as the distance between the masses increases. ● Evaluate the concept that free-fall acceleration near the Earth's surface is independent of the mass of the falling object. ● Demonstrate mathematically how free-fall acceleration relates to weight. ● Describe orbital motion as a combination of two motions.

CH 12.1: Gravity
Objective: Students will be able to explain gravity and how it relates to free fall and projectile motion.
● Explain that gravitational force becomes stronger as the masses increase and rapidly becomes weaker as the distance between the masses increases.
● Evaluate the concept that free-fall acceleration near the Earth's surface is independent of the mass of the falling object.
● Demonstrate mathematically how free-fall acceleration relates to weight.
● Describe orbital motion as a combination of two motions.
