question 21 of 25
which statement accurately describes the relationship between force and momentum?
a. as the density of an object decreases, its momentum decreases, and it takes less force to change its motion.
b. as the mass of an object decreases, its momentum decreases, and it takes less force to change its motion.
c. as the mass of an object decreases, its momentum increases, and it takes more force to change its motion.
d. as the density of an object decreases, its momentum increases, and it takes more force to change its motion.

Explanation:

Momentum ($p$) is given by the formula $p = mv$ (mass times velocity). Force ($F$) is related to the change in momentum ($\Delta p$) over time ($\Delta t$) as $F=\frac{\Delta p}{\Delta t}$. When mass ($m$) decreases with velocity constant, momentum decreases. And a smaller - momentum object requires less force to change its motion.

Answer:

B. As the mass of an object decreases, its momentum decreases, and it takes less force to change its motion.
