What happens to the motion of an object if the resultant force acting on it is not zero?.
- A.It remains at rest or continues to move at constant velocity
- B.It accelerates in the direction of the resultant force
- C.It decelerates to a stop
- D.It moves in a circular path
Model answer
What a good answer should say
- It accelerates in the direction of the resultant force
Explanation
Why this works
According to Newton's second law, if the resultant force is not zero, the object will accelerate in the direction of that force. This is a fundamental principle of motion.
