What does Newton's first law describe?
Understand the Problem
The question is asking about Newton's first law of motion and what it specifically describes in physics. The user is likely looking for a fundamental understanding of one of the key concepts from classical mechanics.
Answer
D. How inertia affects the motion of an object
The final answer is D. How inertia affects the motion of an object.
Answer for screen readers
The final answer is D. How inertia affects the motion of an object.
More Information
Newton's first law, also known as the law of inertia, states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Tips
A common mistake is confusing Newton's first law with the second, which deals with force, mass, and acceleration.
