a parent pushes a single child on a swing. suppose two children now sit on the same swing, and the parent pushes with the same force. according to newtons second law of motion, what is the result? mass increases, acceleration decreases mass decreases, acceleration increases mass increases, acceleration increases mass decreases, acceleration decreases

a parent pushes a single child on a swing. suppose two children now sit on the same swing, and the parent pushes with the same force. according to newtons second law of motion, what is the result? mass increases, acceleration decreases mass decreases, acceleration increases mass increases, acceleration increases mass decreases, acceleration decreases

Answer

Explanation:

Step1: Recall Newton's Second Law

$F = ma$ (where $F$ is force, $m$ is mass, and $a$ is acceleration).

Step2: Analyze the situation

The force $F$ is constant (parent pushes with same force). When two children sit instead of one, mass $m$ increases. From $F = ma$, we can express $a=\frac{F}{m}$. As $m$ increases and $F$ is constant, acceleration $a$ decreases.

Answer:

mass increases, acceleration decreases
