Question 120Gas Turbine - Assistant Engineer
70% to passNewton's First Law of Motion states which of the following?
AA body in a state of rest tends to remain at rest, and a body in motion continues to stay in motion at a constant speed, unless acted upon by some external force.
BA body at rest will remain at rest when an external force is applied.
CA body in motion will continue to stay in motion, when an equal and opposite external force is applied.
DA body in a state of rest tends to remain at rest, and a body in motion continues to stay in motion, when an external force is applied.
AI Explanation
You are correct, the answer is A. Newton's First Law of Motion, also known as the Law of Inertia, states that a body at rest will remain at rest, and a body in motion will continue to move at a constant speed and in a straight line, unless acted upon by an external force. Option A accurately captures this principle - a body at rest tends to remain at rest, and a body in motion continues to stay in motion, unless an external force is applied. The other options either do not fully capture the essence of Newton's First Law or introduce additional conditions that are not part of the law.
