Procedure: 1. Set up an inclined plane by putting one end of the plane on top of a stack of books. Mark the plane for every 40 cm and label these as 40 cm, 80 cm, 120 cm, and so on, starting from the lowest end. 2. Measure the base and the height and calculate the angle of inclination. Use the formula, O = tan (height/base). 3. Roll the tin can from each labelled point starting with the 40 cm mark. Start the timer as the tin can is released, and stop the timer when the tin can has reached the bottom of the inclined plane. 4. Ask your partner to record the time (t) taken by the tin can to travel each distance (d) down the plane. Perform three trials from each mark. Use the table below for your data. 5. Graph d vs. t and then d vs. . TABLE 1.

How will you describe the graphs of: a. distance vs. time? b. distance vs. time?? Q 2. What is the relationship between distance and time of travel of the rolling can? Q 3. What is the slope of d-t graph? What quantity does the slope of d-t graph represent? (Refer to the unit of the slope) Q 4. What do the graphs of distance vs. time and distance vs. time suggest
