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 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. 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.

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 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. 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.

Answer 1

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.

Answer 2

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

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

This is because according to Newton's second law of motion, the net force applied to an object is equal to the product of its mass and acceleration. In this case, both boxes experience the same force of 40 N, but have different accelerations. Since the force is the same for both boxes, a smaller acceleration indicates a smaller mass.

To find the answer, the student compared the accelerations of the two boxes. When the same force is applied, the box with a larger acceleration has a smaller mass, and the box with a smaller acceleration has a larger mass. Hence, the argument that 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.

Answer 3

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