Question

part b
review the results of your second experiment from task 2, part d. when mass is fixed, does an increase in force increase or decrease acceleration? do your results support newton’s second law?

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 relationship when mass is fixed

When $m$ is fixed, if $F$ increases, from the formula $a = \frac{F}{m}$, since $m$ is a non - zero constant, $a$ will increase.

Step3: Determine if results support the law

If in the experiment, when mass was held constant and force was increased, acceleration also increased, then the results support Newton's second law.

Answer:

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