Question
What does Newton's first law state about the motion of an object when the resultant force acting on it is zero?
Answer
Newton's first law states that an object will remain at rest or continue to move at a constant velocity in a straight line unless acted upon by a resultant force.
Explanation
This answer is strong because it accurately reflects the definition of Newton's first law, demonstrating understanding of the concept of resultant force and its effect on motion. The question tests the recall of a fundamental principle in physics.
Common mistake
Misunderstanding Newton's First Law
Students often state that an object will always remain at rest unless acted upon by a force, neglecting that it can also continue moving at constant velocity when no resultant force acts.
Clarify that Newton's first law states that an object will remain at rest or continue to move at a constant velocity unless acted upon by a resultant force, emphasizing both scenarios.
