Exam-style question
Try this first
A 25 kg object is accelerated at 4 m/s². What is the net force acting on the object?.
- A.100 N
- B.25 N
- C.50 N
- D.75 N
Model answer
What a good answer should say
- 100 N
Explanation
Why this works
Using F = ma, where F is the force, m is the mass, and a is the acceleration. Substituting the values: F = 25 kg × 4 m/s² = 100 N.
Therefore, the net force acting on the object is 100 N.
