Air Resistance Open Response

This passage explains the concept of air resistance, a force that opposes the motion of objects moving through the air. Factors such as an object’s shape, surface area, and speed influence the amount of air resistance it encounters. The passage introduces terminal velocity, the point at which the force of gravity and air resistance are balanced, and the object no longer accelerates. Through relatable examples like parachuting and free-falling, readers learn how air resistance affects motion.

This passage expands students’ vocabulary by introducing terms like “terminal velocity” and “air resistance.” It supports comprehension by offering clear, practical examples that help students understand how air resistance operates. Critical thinking is encouraged as students evaluate how different factors like shape and speed influence the force. Additionally, the passage helps with grammar proficiency by presenting complex ideas in straightforward, well-organized sentences.
