Solution
Correct Answer:
A body remains at rest or in uniform straight-line motion unless acted upon by a net external force.
Newton's First Law of Motion, also known as the Law of Inertia, states that every object continues in its state of rest or of uniform motion in a straight line unless it is compelled to change that state by forces impressed upon it.
- Inertia: The inherent property of an object to resist changes in its state of motion.
- Force: Defined qualitatively as the agent that causes a change in the state of motion. If ∑Fext=0, then v=constant.
This easy difficulty physics question is from the chapter laws of motion, covering the topic of newton's first law. It appeared in the 2025 exam.
