Force of Gravity

Data:

Mass (kg)             Force (N)
0.06 kg                0.58 N
0.1 kg                  0.97 N
0.15 kg                1.47 N
0.25 kg                2.46 N
0.55 kg                5.342 N

graph backward  - Force vs, mass, force on y axis!  Did you not look at all of the whiteboards and see yours is backward?

Data Analysis:

Verbal Model: As the mass increases, the force increases proportionally.

Math Model: Force = (9.7045 N/kg) x Mass + 0.0122 N yes but this does not match your graph
                       Fg = mg

Slope: For every one kilogram the mass increases, the force of gravity increases by 9.7045 N.

Y-Intercept: When the mass is zero, the force is 0.0122 N. The y-intercept should be zero because there is no force added at this time because their is no mass attached.

Conclusion:

Claims and Evidence: All the graphs are linear and with a positive slope. The slope (or N/kg) of about 9.8 is going to be the same with everyone because we all did this experiment on Earth, so we all had the same gravitational field. Because the gravitational field is the same, the amount of force per kilogram will remain constant. good! Mass and weight are different because mass is the total amount of stuff the item is made out of and the weight is how much the stuff the item is made out of weighs in total .... no - weight is the force, the pull from the Earth. The amount of force is another way of describing how much the item "weighs." The more mass an object has, the amount of force or "weight" increases. Every item has the same gravitational field even if their masses differ. The amount of Newtons per kilogram multiplied by the amount of mass gives you the amount of force the object will have. This is represented in the equation Fg = mg. good
