Lesson
This lesson introduces the concept of momentum as a vector quantity that describes an object's state of motion, distinguishing it from the scalar nature of kinetic energy. Students will learn to apply the impulse-momentum theorem to analyze collisions and interactions, emphasizing the importance of defining a coordinate system to account for the directional nature of these physical quantities.
