Answer :
Answer:
Actual measurements for KE would be less, due to the transformation of mechanical energy to thermal energy.
Explanation:
If we neglect air resistance, then the potential energy (PE) of a falling object is converted to kinetic energy (KE) only, and the mechanical energy (PE + KE) is constant. However, for an actual falling object, there is air resistance, which causes some of the energy to convert to thermal energy. As a result, the kinetic energy will be less.
