A student is investigating mass and acceleration.

Question

The student applies the same force to two boxes,
as shown in the table.
Box
1
2
Force Applied to Box
(newtons)
20
20
Acceleration (meters/second²)
5
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 less 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 less force than lighter
objects to accelerate at the same rate.

Answer 1

The correct 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.
