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 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. 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. Heavier objects need less force than lighter objects to 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."

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."

Answer 3

The argument that best supports the student's claim is "Heavier objects need greater force than lighter objects to accelerate at the same rate."

To understand why, we can analyze 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. Mathematically, it can be written as:

F = m * a

where F represents the force applied, m represents the mass of the object, and a represents the acceleration.

In this scenario, the student applies the same force of 40 N to both boxes. If we rearrange the formula, we get:

a = F / m

Since the force applied is constant (40 N), and the acceleration is different for both boxes (10 m/s^2 for box 1 and 5 m/s^2 for box 2), we can compare the masses of the two boxes.

If we substitute the given values into the formula, we get:

10 m/s^2 = 40 N / m1 (for box 1)
5 m/s^2 = 40 N / m2 (for box 2)

By rearranging the equation, we can see that the mass of box 1 (m1) must be smaller than the mass of box 2 (m2) to achieve a greater acceleration despite the same applied force.

Therefore, the argument "Heavier objects need greater force than lighter objects to accelerate at the same rate" best supports the student's claim in this scenario.
