Question

1. if an objects mass decreases while a constant force acts on it, the acceleration a) decreases. b) remains the same. c) increases. d) will be zero.

Explanation:

Step1: Recall Newton's second - law

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

Step2: Analyze the change

Given that $F$ is constant and $m$ decreases. Since $a=\frac{F}{m}$, when the denominator $m$ of a fraction decreases while the numerator $F$ is constant, the value of the fraction (acceleration $a$) increases.

Answer:

C. increases
