Question
A student is investigating mass and acceleration. The student applies the same force of 40 N force to two boxes that have the same size and shape. Box 1 experiences an acceleration of 10 m/s^2 and box 2 experiences an acceleration of 5m/s^2.

The student claims that box 1 must have a smaller mass than box 2. Which argument best supports the student's claim?(1 point)

Answer 1

The correct answer is: "Lighter objects need less force than heavier objects to start moving but will accelerate at the same rate." This argument supports the student's claim because it explains that box 1, which experiences a higher acceleration, must have a smaller mass than box 2, which experiences a lower acceleration.
