Fill in the blanks by selecting an appropriate option.
Newton's first law of motion states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an external force. This law is also known as the law of (i). It implies that in the absence of a net force, the (ii) of an object remains constant.
  • a)
    (i) - Inertia, (ii) - speed
  • b)
    (i) - Motion, (ii) - velocity
  • c)
    (i) - Inertia, (ii) - velocity
  • d)
    (i) - Action, (ii) - speed
Correct answer is option 'C'. Can you explain this answer?

Understanding Newton's First Law of Motion
Newton's first law of motion is fundamental in understanding the behavior of objects in different states of motion. It highlights the concept of inertia and its implications on motion.
Key Concepts of the Law
- An object at rest will stay at rest.
- An object in motion will continue in motion.
- These states remain unchanged unless acted upon by an external force.
Explanation of the Options
- (i) Inertia: This term describes an object's resistance to change in its state of motion. It is directly related to Newton's first law, which is often referred to as the law of inertia.
- (ii) Velocity: This term refers to the speed of an object in a specific direction. When no net external force acts on an object, its velocity (magnitude and direction) remains constant.
Correct Option: C
The correct answer is option (C), which states:
- (i) Inertia
- (ii) Velocity
Why Option C is Correct
- The term "inertia" captures the essence of the law, emphasizing that an object will maintain its state of rest or uniform motion.
- "Velocity" is more comprehensive than just "speed" because it includes both speed and direction. In the absence of a net force, both the speed and direction of the object's movement remain unchanged.
Conclusion
In summary, Newton's first law highlights that the natural state of an object is to maintain its current state unless influenced by external forces, encapsulated in the terms "inertia" and "velocity." Understanding these concepts is crucial for studying motion in physics.
