Question 1 Multiple Choice
Two boxes are pushed with the same force. Box A has a mass of 2 kg and Box B has a mass of 4 kg. Which box accelerates more?
ABox B, because it is heavier
BBox A, because it has less mass
CThey accelerate equally
DNeither accelerates because the forces are the same
According to a = F/m, when force is the same, the object with less mass has greater acceleration. Box A (2 kg) accelerates twice as much as Box B (4 kg).
Question 2 True / False
If you double the net force on an object while keeping its mass the same, the acceleration doubles.
TTrue
FFalse
Answer: True
From a = F/m, acceleration is directly proportional to force. Doubling the force doubles the acceleration when mass is unchanged.
Question 3 Short Answer
A 10 N net force acts on a 5 kg object. What is its acceleration?
Think about your answer, then reveal below.
Model answer: 2 m/s², because a = F/m = 10/5 = 2.
Using Newton's Second Law, a = F/m = 10 N / 5 kg = 2 m/s².
