Unformatted text preview: PE total , KE total , E total , E bond , E thermal . (Remember that E total can be expressed as either a sum of PE and KE, or as a sum of the macroscopic energy systems E bond and E thermal , i.e., E total = PE + KE = E bond + E thermal ) 3.2-2b) After an amount of energy is added to the system, the three particles begin to oscillate. At a particular point in time the three particles are momentarily at rest , as shown below. i) Have any bonds been broken? What does you answer imply about E bond ? ii) Determine the following: PE total , KE total , E total , E bond , E thermal . r = r r = r r = 1.5 r r = 1.25 r 3.2-2c) For the amount of total energy in part ( b ), which of the 5 values that you found in part ( b, ii ) are constant in time? Explain . 3.2-2d) For the particular configuration of the three particles in part ( b ) the thermal energy is all PE. Will that be true at all points in time for that amount of total energy? Explain ....
