Question

3. For the Constant Total Mass data (Table 1), plot (by hand) a graph of F s a, and draw a linear fit. (a) What physical quantity does the slope of the best-fit line represent? (b) Calculate the % Error between this quantity and your slope. 5. For the Constant Net Force data (Table 2), plot (by hand) a graph of aesp vs 1/M, and drav linear fit. 6. (a) What physical quantity does the slope of the best-fit line represent? (b) Calculate the % Error between this quantity and your slope. 7. Explain how the Force vs. Acceleration plot relates to Newton's Second Law. The Face s. Acceleoken plot reloes to eton's Second relotes to Neuston's

Explanation / Answer

(4) (a)Actually slope represent a physical quantity which depend upon the ratio of other two physical quantity.
For eg. Velocity = Distance /time
So in the graph of distance and time , slope would represent velocity
Similarly acceleration = Velocity / time
SO in the graph of velocity and time
Slope will represent acceleration.
(b) percentage error = ((Calculted value - given value ) / Given value)*100
(data is not mentioned)
(7) According to the second law force depends upon the acceleration
If we want to produce more acceleration we have to apply more force.
So force vs acceleration diagram show the relation of the force and acceleration which
is given by the second law.
therefore this graph is showing the relation of second law.
