What is the first law of motion also known as?
Show answer & explanation
Correct answer: D
Explanation
Correct Answer:
Option 4: Law of Inertia
Explanation:
Newton's First Law of Motion is based on the principle of inertia. According to this law, an object remains in its state (either at rest or in uniform motion) unless acted upon by an external force. This is known as the Law of Inertia. It is a fundamental principle of physics, and numerous examples of it can be observed in daily life—such as the body lurching forward when brakes are applied suddenly.
Additional Facts:
Option 1: Acceleration corresponds to the Second Law.
Option 2: Action-Reaction corresponds to the Third Law.
Option 3: Momentum is a distinct concept.
Option 4: Correct Answer.
