Question 4 A student is investigating mass and acceleration. The student applies the same force to two
boxes, as shown in the table.
Force Applied to
Box
Box (newtons)
1

Acceleration
(meters/second)
5
2
20
2
The student claims that box 1 must have a smaller mass than box 2. Which argument best
supports the student's claim?
A
Heavier objects require less force than lighter objects to accelerate at the
same rate
Heavier obiecte
