Answer

Explanation:

Step1: Recall Newton's second - law formula

Newton's second law is $F = ma$, where $F$ is the net force, $m$ is the mass and $a$ is the acceleration. We can rewrite it as $a=\frac{F}{m}$.

Step2: Analyze the case when mass is constant

When the mass $m$ is constant, $a$ is directly proportional to $F$. If the net - force $F$ doubles, from $F_1$ to $F_2 = 2F_1$, then $a_1=\frac{F_1}{m}$ and $a_2=\frac{F_2}{m}=\frac{2F_1}{m}=2a_1$. So doubling the net force increases the acceleration 2 times when the mass is constant.

Step3: Analyze the case when force is constant

When the force $F$ is constant, $a$ is inversely proportional to $m$. If the mass doubles, from $m_1$ to $m_2 = 2m_1$, then $a_1=\frac{F}{m_1}$ and $a_2=\frac{F}{m_2}=\frac{F}{2m_1}=\frac{1}{2}a_1$. So doubling the mass decreases the acceleration by half when the net force is constant.

Answer:

A doubling of the net force increases acceleration 2 times when the object's mass is constant; A doubling of the mass decreases the acceleration of the object by half when the net force is constant.
