Question

EXPERIMENTSU Uniformly Acelerated Motion TI QUESTIONS A. Object in Free Fall 1. Objects of different mass were used to see whether the acceleration due to gravity depends on the mass of a falling object. In other words, does a heavier object fall faster than a lighter object? What do your experimental results show? 2. What is probably the greatest source of error in the experimental procedure? B. Linear Air Track 3. What are the major sources of error in this procedure? What would be the shapes of the curves for a graph of y versus f of the data in each experimental case? How would you determine the value of the car's acceleration from a graph using only y and r values (that is, not computing y)? 4.

Explanation / Answer

1.

No , all the objects take same time in falling irrespective of the mass of the objects.
hence , a heavier object doesn't fall faster than the lighter object.

experimetal results also show the same.

2.

the sources of error is :

i. Air resistance force

ii. human error due to timing measurement

3.

For the soruces of error :

i. Air resistance force

ii. human error due to timing measurement

5.

the slope of graph for the air track shows that

slope = g * sin(theta)

the slope of the graph is g * sin(theta)
