Question

part a
review the results of your first experiment from task 2, part b. when force is fixed, does an increase in mass increase or decrease acceleration? the equation for newtons second law is $f = ma$. do your results support newtons second law?

Explanation:

Step1: Rearrange Newton's second - law formula

Given $F = ma$, we can solve for $a$ as $a=\frac{F}{m}$.

Step2: Analyze the relationship

When $F$ is fixed (constant), if $m$ increases, since $a=\frac{F}{m}$, the value of $a$ will decrease because we are dividing a constant $F$ by a larger number $m$.

Step3: Check if results support the law

If the experimental results show that as mass increases and force is held constant, acceleration decreases, then the results support Newton's second - law.

Answer:

When force is fixed, an increase in mass decreases acceleration. If the experimental results show this trend, they support Newton's second law.
