A 2 kg object accelerates to the right at 4 m/s^2. What is the net force acting on it?

• A. 4 N
• B. 12 N
• C. 8 N
• D. 6 N

Answer: (C)

Net force equals mass times acceleration, F_net = m a. With a mass of 2 kg accelerating to the right at 4 m/s^2, the net force is 2 × 4 = 8 N, directed to the right. The value 8 N matches the given acceleration and mass; other numbers would require different accelerations for the same mass (for example, 4 N would imply 2 m/s^2, 12 N would imply 6 m/s^2).
