Question

1. state newtons second law of motion.
2. what happened to the acceleration rate as you used only 100 g mass?
3. what was being decreased as you added masses?

Explanation:

Newton's second law of motion states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration ($F = ma$). When only a 100 - g mass is used (assuming force is constant), according to $a=\frac{F}{m}$, with a smaller mass, the acceleration should increase. When masses are added (assuming force is constant), according to $a = \frac{F}{m}$, the acceleration is being decreased.

Answer:

1. Newton's second law of motion: The net force ($F$) acting on an object is equal to the mass ($m$) of the object multiplied by its acceleration ($a$), i.e., $F=ma$.
2. If force is constant, when using only a 100 - g mass (smaller mass), the acceleration should increase (not slow down as wrongly written in the original).
3. When masses are added (assuming force is constant), the acceleration is being decreased.
