Exam-style question
Try this first
If an object has a mass of 5 kg and is accelerating at 2 m/s², what is the resultant force acting on it?.
- A.10 N
- B.7 N
- C.5 N
- D.2 N
Model answer
What a good answer should say
- 10 N
Explanation
Why this works
Using Newton's second law, F = m × a. Substituting the values: F = 5 kg × 2 m/s² = 10 N.
This is the resultant force acting on the object.
