which quantity may be calculated directly using newtons second law of motion?\nweight\nvelocity\nposition\ndi…

Answer:

weight

Explanation:

Step1: Recall Newton's second - law

$F = ma$.

Step2: Recall weight formula

Weight $W=mg$, where $g$ is acceleration due to gravity. It is a special case of $F = ma$ with $a = g$.

Step3: Analyze other options

Velocity, position and direction cannot be directly calculated from $F = ma$. Velocity requires integration of acceleration over time, position requires double - integration of acceleration over time, and direction is not a quantity directly obtained from $F=ma$.
