Ch 2: Free Fall


Free fall continues the study of motion in one dimension, but with a focus on the effects of gravity on objects falling freely near the surface of the Earth. Gravitational attraction between the Earth and objects cause them to accelerate toward the Earth and are said the be 'falling'. Acceleration due to gravity is given a special symbol 'g' and has a value of 9.8 m/s^2. The acceleration 'g' VECTOR points directly toward the center of the Earth. In a later chapter we will look more closely at gravitational force, accepting for now that objects in free fall accelerate at 9.8 m/s^2. There is good here... we can neglect air resistance (friction) for the most part in this chapter!
