Question

A group of students took the following data during their physics lab. Graph the data in the space provided and answer the following questions. A) What did the students taking this data do differently in Test 1 and Test 2? B) Do you think the data on the graph should pass through the origin? Why or why not?

A group of students took the following data during their physics lab. Graph the data in the space provided and answer the following questions. What did the students taking this data do differently in Test 1 and Test 2? Do you think the data on the graph should pass through the origin? Why or why not?

Explanation / Answer

b. Both the data plot passes through origin.

1st test equation is y= 0.1*x

2nd test equation is y = 0.04 *x

a. in the equations y is frictional force and x if the normal force.

and the slope is coefficient of friction.

since slope is different in both the cases, coefficient of friction is different and coefficient of friction is material dependent.

So, in both tests different materials are being used
