Introduction
Newton's third law of motion states that for every action, there is an equal and opposite reaction. This fundamental principle is crucial in understanding the forces that act between objects in a closed system. In this article, we will explore the concept of Newton's third law and apply it to a real-world scenario involving Ana and a volleyball. We will examine the force exerted by Ana on the volleyball and determine the force that the volleyball exerts on Ana.
Newton's Third Law of Motion
Newton's third law of motion is a fundamental concept in physics that describes the relationship between two objects that interact with each other. According to this law, when object A exerts a force on object B, object B will exert an equal and opposite force on object A. This law can be mathematically expressed as:
F_A → B = -F_B → A
Where F_A → B is the force exerted by object A on object B, and F_B → A is the force exerted by object B on object A.
The Scenario: Ana and the Volleyball
In this scenario, Ana exerts a force of 20 N on a volleyball that has a mass of 0.15 kg. We are asked to determine the force that the volleyball exerts on Ana. To solve this problem, we can apply Newton's third law of motion.
Applying Newton's Third Law
According to Newton's third law, the force exerted by the volleyball on Ana is equal and opposite to the force exerted by Ana on the volleyball. Therefore, we can write:
F_volleyball → Ana = -F_Ana → volleyball
Since F_Ana → volleyball = 20 N, we can substitute this value into the equation above:
F_volleyball → Ana = -20 N
However, we are asked to determine the magnitude of the force exerted by the volleyball on Ana, not its direction. Therefore, we can take the absolute value of the force:
|F_volleyball → Ana| = 20 N
The Correct Answer
Based on our analysis, the correct answer is:
B. 20 N
Conclusion
In this article, we applied Newton's third law of motion to a real-world scenario involving Ana and a volleyball. We determined that the force exerted by the volleyball on Ana is equal and opposite to the force exerted by Ana on the volleyball, and therefore, the magnitude of the force exerted by the volleyball on Ana is 20 N.
Additional Considerations
It's worth noting that the mass of the volleyball is not relevant to the calculation of the force exerted by the volleyball on Ana. According to Newton's third law, the force exerted by object B on object A is independent of the mass of object B.
Real-World Applications
Newton's third law of motion has numerous real-world applications in fields such as engineering, physics, and sports. For example, in sports, the force exerted by a player on the ball is equal and opposite to the force exerted by the ball on the player. This principle is crucial in understanding the dynamics of various sports, such as tennis, basketball, and soccer.

Introduction
Newton's third law of motion is a fundamental concept in physics that describes the relationship between two objects that interact with each other. In our previous article, we applied this law to a real-world scenario involving Ana and a volleyball. In this article, we will answer some frequently asked questions about Newton's third law of motion.
Q: What is Newton's third law of motion?
A: Newton's third law of motion states that for every action, there is an equal and opposite reaction. This means that when object A exerts a force on object B, object B will exert an equal and opposite force on object A.
Q: What is the difference between action and reaction forces?
A: Action and reaction forces are two forces that act on different objects in a closed system. The action force is the force exerted by one object on another, while the reaction force is the force exerted by the second object on the first.
Q: Can you give an example of Newton's third law of motion?
A: Yes, a classic example of Newton's third law of motion is a tennis racket and a tennis ball. When a tennis player hits a tennis ball with a racket, the racket exerts a force on the ball, and the ball exerts an equal and opposite force on the racket.
Q: Is Newton's third law of motion always true?
A: Yes, Newton's third law of motion is always true. It is a fundamental principle of physics that describes the relationship between two objects that interact with each other.
Q: Can you apply Newton's third law of motion to a real-world scenario?
