Which statement is Newton's first law?
Answer and explanation
Correct answer: D. A body keeps its state of rest or uniform motion unless a net force acts on it
- Step 1: The first law is the law of inertia. Step 2. Without a net force, velocity stays constant. Answer: A body keeps its state of rest or uniform motion unless a net force acts on it. Why not the others: these describe other laws or are wrong.
