Question

fill in the blank question
if you wish to increase an objects acceleration without changing the force on the object, you must the objects mass.

Explanation:

This relies on Newton's second law of motion, expressed as $F = ma$ (force equals mass times acceleration). Rearranged to solve for acceleration, it is $a = \frac{F}{m}$. When force $F$ is constant, acceleration $a$ is inversely proportional to mass $m$. To increase acceleration, mass must be decreased.

Answer:

decrease
