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) Responses Heavier objects need greater 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 greater force than heavier objects to start moving but will accelerate at the same rate. Lighter objects need greater force than heavier objects to start moving but will accelerate at the same rate. Lighter objects need less force than heavier objects to start moving but will accelerate at the same rate. Lighter objects need less 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 less force than lighter objects to accelerate at the same rate.

Answer 1

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

Answer 2

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 argument suggests that since both boxes experience the same force of 40 N, but box 1 has a higher acceleration than box 2, it implies that box 1 must have a smaller mass because heavier objects require more force to achieve the same acceleration.

Answer 3

The argument that best supports the student's claim is: Lighter objects need less force than heavier objects to start moving but will accelerate at the same rate.

To understand why this argument is correct, we need to recall Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. This relationship can be expressed by the equation F = m * a, where F is the force applied, m is the mass of the object, and a is the acceleration produced.

In the given scenario, the same force of 40 N is applied to both boxes. Box 1 experiences an acceleration of 10 m/s^2, while box 2 experiences an acceleration of 5 m/s^2. According to Newton's second law, the acceleration produced by a force is inversely proportional to the mass. Therefore, if box 1 accelerates more than box 2 with the same force, it must have a smaller mass than box 2. This aligns with the student's claim that lighter objects need less force to accelerate at the same rate.

Hence, the argument that best supports the student's claim is that lighter objects need less force than heavier objects to start moving but will accelerate at the same rate.
