Mass vs. Force

Purpose: In class last week we learned about the relationship between mass and force. We discovered that by weighing different sizes of metal we will find the pattern between mass and force. The pattern of mass and force helps us know how much

Key Information:  In our lab we weighed 5 different sizes of metal, which were 1kg, .5kg, .2kg, .1kg, and .02 kg, and found out that the mass in 1kg requires 10 times the force in Newtons, meaning that for every 1kg there are 10 newtons. Then, once we graphed the the mass and force we talked about the best fit line, which is the pattern or theory of the lab. In this case our pattern is 10 N/kg.

Key Conclusion:  After graphing, we found out the slope/pattern by using y= mx + b. Y represents the dependent  variable, m represents the slope, x represents the independent variable, and b represents the y-intercept, which is happens to be 0 in our lab. In this case, we ended up with F= gm. F stand for force of gravity or weight, g stands for gravity( 10 N/kg ), and m stand for mass. As a result of figuring out the slope/pattern we got F= 10 N/kg m .Now that we know this, we can figure out how much force is needed upon a certain amount of mass whether on earth or another planet. Here's a visual of our lab:

This link is a real life example of mass, gravity, and force because it shows us how the mass of something effects the force on gravity compared to the earth and moon. In our lab we weighed the metals and figure out how much force is needed in 1kg(mass) on earth but on the moon we discovered that there is less force on the metals when on the moon. In this youtube video, the man on the moon is able to move and jump high in his 70 lb suit because there is less force needed on the mass of the suit and man.
