Introduction to Collisions: Momentum, Impulse, and Impact Types

Miacademy & MiaPrep Learning Channel

This engaging physics video serves as an introduction to a unit on collisions, moving beyond single-object motion to the interaction between two objects. It systematically breaks down the core concepts necessary to understand these interactions: momentum, impulse, and the classification of collisions as either elastic or inelastic. The video utilizes clear real-world examples ranging from container ships and butterflies to sports like pool, golf, and kickboxing to illustrate abstract physical properties. Key themes include the mathematical definition of momentum ($p=mv$), the Law of Conservation of Momentum, the relationship between force and time in creating impulse ($Δp = FΔt$), and the distinction between objects bouncing (elastic) versus sticking together (inelastic). The content connects mathematical formulas directly to observable phenomena, such as why follow-through is important in sports. For educators, this video is an excellent hook and foundational overview for a high school physics unit on mechanics. It provides clear definitions, introduces essential formulas, and offers ready-made visual analogies that can be analyzed in class. It is particularly useful for visual learners who need to see the connection between equations and physical actions, such as a golf swing or a car crash.
