SECOND

In part one of the experiment, you are dropping an object with a calibrated set of markings on through a photogate device. The computer collects the data and graphs it. What data are you mainly interested in? (choose the best answer) O the velocity vs time O the distance traveled vs time O the acceleration none of the above Save Question 2 (1 point) How do you relate the slope of your graph (acceleration vs. (M2-M1)) to the gravitational constant g? O g=slope/(M2-M1) O g=slope/(M1+M2) O g-slope (M2-M1) g-slope (M1+M2) Save Question 3 (1 point) In each of the three parts of this lab, you collect a set of data points by varying one variable (the x data point) and collecting (related to the y data point) O The centripetal force value The calibration weight value O O The time it takes for 10 revolutions of the armature The spring height value Save

Explanation / Answer

Part-1 :

(a) In part one of the experiment, you are dropping an object with a calibrated set of marking on through a photogate device. The required data which are mainly interested in it which given as :

the velocity vs. time

(b) To relate the slope of graph (acceleration vs. M2 - M1) to the gravitational constant, g which is given as :

g = slope * (M1 + M2)

(c) In each of the three parts of this lab, we collect a set of data points by varying one variable (the x data point) and collecting the spring height value (related to the y data point).

Part-2 :

(d) False

(e) True

(f) For data analysis, we need to obtain by plotting the data for each part which is given as :

The slope of the best fit line
