How we investigated the big question: For this lab, my group hung brass masses from a force probe and measured the amount of force needed to support it. We recorded the data for four different masses. We then put plotted our points into a graph. The mass in kilograms was on the x-axis and the force in newtons was on the y-axis. We then created a best fit line. We found the slope using g for the gravitalonal constant and used it for the equation force= 10 N/Kg m+ 0. The gravitational constant varies for each planet.
Answer to the big question: The force it takes to hold an object in place is 10 newtons per each kilogram.
Evidence of conclusions: For 1000 gram or 1 kilogram brass mass, we got a force of 10. 172 Newtons, which can be rounded to 10 Newtons. As wheel as the fact that we got a force of 5. 546 Newtons for our 5 kilogram or 500 gram brass mass.
How I can use what I learned in a new situation: I can use what I learned in order to find the force needed to hold an object in place in different situations or on different planets. I can also used what I learned in using the slope in the equation in many other problems.
How this relates outside of class: This relates to volleyball and how much force it takes to hit the ball over the net. Different amounts of force are required to perform all the different techniques in volleyball.
Good job overall. You may want to write something about "g" being the slope of your fit line and how it varies for other planets.
