Exam-style question
Try this first
If a 10 kg object is moving with a constant velocity, what can be said about the resultant force acting on it?.
- A.It is equal to 10 N
- B.It is greater than 0 N
- C.It is less than 0 N
- D.It is 0 N
Model answer
What a good answer should say
- It is 0 N
Explanation
Why this works
An object moving with constant velocity has no acceleration, which means the resultant force acting on it is zero according to Newton's first law of motion.
