Question
- A. The resultant force is zero.
- B. The resultant force is equal to its weight.
- C. The resultant force is equal to its mass.
- D. The resultant force is acting in the direction of motion.
Answer
The resultant force is zero.
Explanation
When an object moves at a constant velocity, it means that there is no net force acting on it, hence the resultant force is zero.
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.
