Review Questions

• How does Giancoli explain the relationship between linear momentum and velocity?
  • Giancoli explains that linear momentum is directly proportional to both the mass and velocity of an object, represented by the formula $$p = mv$$, where $$p$$ is momentum, $$m$$ is mass, and $$v$$ is velocity. This means that if either mass or velocity increases, the momentum will also increase. The textbook emphasizes understanding this relationship as crucial for analyzing motion in various physical situations.
• In what ways does Giancoli illustrate the concept of conservation of momentum through examples?
  • Giancoli uses practical examples such as collisions between billiard balls or cars to demonstrate conservation of momentum. It shows that in isolated systems, the total momentum before an event equals the total momentum after the event. By analyzing these examples, readers learn how to apply conservation principles to solve problems involving varying masses and velocities.
• Evaluate how Giancoli connects angular momentum with real-world applications in sports biomechanics.
  • Giancoli connects angular momentum to sports biomechanics by examining activities like gymnastics or diving, where athletes need to control their rotational motion for optimal performance. The text explains how understanding angular momentum helps athletes adjust their body positions during flips or spins to achieve desired outcomes. This connection illustrates the importance of physics principles in improving athletic techniques and performance.

Conservation of Momentum: This principle states that in a closed system, the total momentum before and after an event remains constant, as long as no external forces act on it.

Torque: Torque is a measure of the rotational force applied to an object, influencing its angular momentum and resulting in rotational motion.
