Mass VS. Force Lab

The purpose of this lab was to correlate the relationship between the mass (m) and force (F) of an object. Through the use of a manual force probe and an electrical one, we were able to collect data and produce graphs that show how many newtons (N) of force were needed for the various masses (kg). During this lab, we also learned more about the scientific usage of a best fit line.

Important Info and Lab Summary: When trying to find the amount of force (F) needed for the various brass masses, we had to use a force probe - both manual and electronic. From the probe, we were able to hang each mass and measure the amount of force in newtons (N) that were exerted on it. One of the most challenging part of the labs was keeping the electric force probe steady, making the results as accurate as possible.

Key Data: 
- Mass of object (independent variable) lays on the x-axis
- Force (dependent variable) lays on the y-axis
- Once graphed we found the slope of the line (slope = 10 N/kg)
- By using the slope we were able to figure out the equation F=mg
- F=mg provides us with a constant equation to calculate the force of gravity on earth which turns out to be about 10 times the mass (kg) of an object

Relationship to the real world:
This lab is super easy for us to see in our own lives. Through this activity I have learned that with an increase of mass, there is also an increase of force being exerted on that mass object. This law of the more mass the more force needed, is present in our lives when exercising. When lifting weights for example, a 5 pound weight is much easier to lift than a 25 pound weight. This is because the gravitational pull is stronger on the 25 pound weight than it is on the 5 pound weight due to the fact that less mass is present, and less force is needed!
