... initial height completing 1 cycle in a total time of 2.8 seconds. It will continue doing this oscillating up and down. However, this is not simple harmonic because to be simple harmonic the force should vary directly proportional to the displacement but that is not the case in this situation ...

... It is the energy associated with a chemical reaction that can be used to do work and is the sum of its enthalpy (H) plus the product of the temperature and the entropy (S) of the system. This quantity can be defined as: G=H−TS or more completely as G=U+PV−TS where •U = internal energy (SI unit: joul ...
