Question
1.In this problem we wish to contrast two different measurement processes. Here are the two measurements: I. We measure the mass of an object using an equal arm balance, where the object is placed on one pan and standard masses are put on the other pan until they balance out. II. We measure the net force acting on an object and the acceleration of the object, and then we divide the net force by the acceleration. a) Without using the word mass, state as simply as you can what property of the object is being measured in case I. b) Again without using the word mass, state what property of the object is being determined in case II. c) Based on the discussion so far, is it all obvious that these two measurements are related to each other? d) At one time the terms “inertial mass” and “gravitational mass” were used to describe the results of the two measurement processes described. Which term would you use for which process?
Explanation / Answer
a) inertial property of the bady is found under the external force.
b) inertial property of the body is found under the action of gravitational force.
c) two definition of mass are quite independentt of the each other. there is no obvious reson why the two should be identical. However, they happen to be identical. Several sophisticated experiments have been performed to test this equivalence and none of them has supplied any evidence against it. the general theroy of relativity is based on the principle of equivalence of inertial and gravitational mass.
d) by the priniciple of equavalence, inertial and graitational mas both are equivalence to each other. so, we can use any one can be used for any process.
