5A what is a Newton?

Problem Statement

What is the relationship between weight and mass?

Purpose

The purpose of this experiment is to find out what correlation there is between mass and newton.

Hypothesis

If acceleration (the gravitational constant) is held constant and mass increases, then weight will increase, because there is direct proportionality between mass and weight.

Materials

15 Washers
Triple beam balance
Spring scale
Scientific calculator (Texas instrument TI-34 MultiView)

Procedures

1. Before using spring scale calibrate it by turning the chestnut on the top until the plunger lines up with the zero mark.
2. Grab the amount of washers that were needed for use in the beginning of the experiment : 3 washers.
3. Place first three washers through the thread and hang it on the bottom of the spring scales hook.
4. Measure weight in newtons and record data.
5. Place and additional three washers (total of 6) through the thread and hang it on the bottom of the spring scales hook.
6. Measure weight in newtons and record data
7. Place and additional three washers (total of 9) through the thread and hang it on the bottom of the spring scales hook.
8. Record weight in newtons and record data
9. Place and additional three washers (total of 12) through the thread and hang it on the bottom of the spring scales hook.
10. Measure weight in newtons and record data
11. Place and additional three washers (total of 15) through the thread and hang it on the bottom of the spring scales hook.
12. Using triple beam balance, place washers at intervals of 3 starting with 3 washers and ending with 15 washers and record mass.
13. Convert grams into kilograms by dividing by 1000.

Results

For the trial with three washers the weight in newtons was less than zero (approximately 0.001 N) and the mass in grams was 18.7. The trial with six washers had a weight of less than zero (approximately 0.002 N) and had a mass of 35.5 g. The trial with nine washers had a weight of less than zero (approximately 0.004 N) and a mass of 36 g. For the trial with twelve washers the weight is approximately 0.007 N and had a mass of 47.5 grams. For the trial with fifteen washers the weight is approximately 0.1 N with a mass of 56.7 grams. The table below shows the aforementioned data with an additional column that shows the conversion of grams to kilograms.
