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 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.
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 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.
The correct response is: Lighter objects need less force than heavier objects to start moving but will accelerate at the same rate.
Are you sure explain
Yes, I am sure. The statement "Lighter objects need less force than heavier objects to start moving but will accelerate at the same rate" supports the student's claim that box 1 must have a smaller mass than box 2.
According to Newton's second law of motion, F = ma, where F represents the force applied, m represents the mass of the object, and a represents the acceleration experienced by the object.
In this case, the student applies the same force of 40 N to both boxes. However, box 1 experiences a higher acceleration of 10 m/s^2, while box 2 experiences a lower acceleration of 5 m/s^2.
Since the force applied is the same, and the acceleration experienced is different, according to Newton's second law, the only variable that can account for this difference in acceleration is the mass of the objects.
Therefore, if box 1 has a higher acceleration than box 2 despite the same force being applied, it means that box 1 must have a smaller mass than box 2. This aligns with the student's claim.
