Acceleration is described as exactly inversely proportional to which quantity?
AThe mass
BThe time
CThe distance
DTemperature
Answer & Solution
Correct answer: A. The mass
1. The second law is built from two proportionalities.
2. Experiments established how acceleration depends on force and mass.
3. Acceleration is exactly inversely proportional to mass.
4. It is exactly linearly proportional to the net external force.
