Question
What happens to an object's motion when a non-zero resultant force acts on it?
Answer
When a non-zero resultant force acts on an object, it causes the object to accelerate in the direction of the resultant force. This means that the object's velocity will change, either increasing or decreasing depending on the direction of the force relative to the object's motion.
Explanation
This question tests the understanding of Newton's second law of motion, specifically how forces affect motion. The answer demonstrates comprehension of the relationship between force and acceleration.
Common mistake
Misunderstanding Resultant Force
Students often think that a non-zero resultant force means the object will always speed up, ignoring the possibility of changing direction.
Clarify that a non-zero resultant force causes acceleration, which can be an increase or decrease in speed or a change in direction.
