Question
What does it mean for an object to remain at rest when the resultant force is zero?
Answer
When the resultant force acting on an object is zero, it means that all the forces acting on the object are balanced. As a result, the object will not change its state of motion and will remain stationary.
Explanation
This answer demonstrates an understanding of Newton's first law of motion, which states that an object at rest will stay at rest unless acted upon by a net external force. The question tests the student's ability to explain a fundamental concept in physics.
Common mistake
Confusion about Forces
Students often think that an object at rest will start moving if no forces are acting on it.
Remember that an object at rest remains at rest when the resultant force is zero. Reinforce the concept that it is the presence of a non-zero resultant force that causes motion.
