Problem:
What is the relationship an object’s mass and an object’s weight?
Design:
In this lab, we are finding the relationship between an object’s mass and an object’s weight by creating a graph that represents the gravitational field strength. On the graph, the mass of the object (m) was located on the x-axis because it’s the independent variable. The weight of the object (Fg) is on the y-axis since it’s dependent on the mass of the object. The values found on the x-axis were directly taken from a triple beam balance and converted into kilograms. On the y-axis, the weight values derived from the formula Fg = mg since the weight is equivalent to the force of gravity. We know these two values are equivalent because …show more content…
Be sure to increase the masses of the weight(s) consecutively each trial.
2.) Attach the weight(s) to the spring scale and measure the spring force, Fs, in newtons (N) as seen on the scale. Record the spring force with the corresponding mass used.
3.) Repeat the first two trials until 7 trials have been performed and recorded. When using the weights, be sure to not exceed .45kg in any trial.
4.) When all the masses are recorded with their corresponding spring forces, calculate the weight force, Fg, and record.
5.) Create a graph where mass is the independent variable on the x-axis and weight is the dependent variable in the y-axis. Use the points from the data table to create a graph and find the line of best fit.
6.) Calculate the slope of the line and use two points on the line of best fit to find the force of gravity in the lab.
7.) Once the slope is calculated, use the equation Experimental - TheoreticalTheoretical x 100 to find the percent error. Use the slope calculated as the experimental gravitational field strength and use 9.8 N/kg as the actual gravitational field
