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 10m/s

Question

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)

Lighter objects need greater force than heavier objects to start moving but will accelerate at the same rate.

Heavier objects need less force than lighter objects to accelerate at the same rate.

Heavier objects need greater force than lighter objects to accelerate at the same rate.

Lighter objects need less force than heavier objects to start moving but will accelerate at the same rate.

Answer 1

The argument that best supports the student's claim is:

Heavier objects need greater force than lighter objects to accelerate at the same rate.

This statement implies that if both boxes experience the same force but have different accelerations, the box that accelerates more (Box 1 with 10 m/s²) must have a smaller mass compared to the box with the lesser acceleration (Box 2 with 5 m/s²), which aligns with the student's conclusion.
