Newton's First Law of Motion is also known as the Law of:
A. Gravitation
B. Action and Reaction
C. Momentum
D. Inertia
Answer: Option D
Solution (By JKSSB Mock Tests)
Newton's First Law states that a body at rest stays at rest, and a body in motion stays in uniform motion unless acted upon by an external unbalanced force. This inherent property of matter to resist any change in its state of rest or motion is called inertia, hence it is known as the Law of Inertia.
