Physics Class 9 Practical 8 Important Viva Questions with Answers (Value of g by Atwood Machine)
PRACTICAL 8 To determine the value of 'g' by Atwood's Machine VIVA VOCE 1. What is the purpose of conducting the Atwood's machine experiment? Ans: The purpose is to determine the acceleration due to gravity (g) using the Atwood's machine setup. 2. Describe the Atwood's machine setup. Ans: The Atwood's machine consists of a pulley with a string passing over it. Two masses of different weights are suspended on either end of the string. 3. How does the Atwood's machine work? Ans: When the masses are released, they experience a net force due to the difference in their weights. This causes an acceleration of the system. 4. What is the relationship between the masses and the acceleration in Atwood's machine? Ans: According to Newton's second law, the acceleration of the system is directly proportional to the net force acting on it, which is the difference in weights of the masses. 5. How will you measure the acceleration in the Atwood'
