Respuesta :

Answer: option d. all of the above.


Justification:


In all the cases you use the fact tha energy can be transformed in other forms of energies.



1) Move:


Motion is the expression of kinetic energy. For example, when drop an object, its potential energy will transform into kinetic energy making the object move.


2) Change:


Energy can modify the form of an object, either by the modification of the position of the molecules (atoms) by, for example, compression, or by the change of phase (heat energy can cause change of phases: solid, liquid, gas).


3) Work:


The change of mechanical energy is work: an object falling attached to other object through a rope and a pulley, may lift the second, doing workg that is equal to the change of the mechanical energy of the first.
