☆☆☆☆☆Gravitational potential energy is the potential energy an object has due to its position in a gravitational field. The higher an object is the greater its gravitational potential. When it falls the gravitational potential becomes kinetic energy.
Energy stored in height differences ~APEX
It is another form of potential stored in food, batteries, and fuel.
Solids change their shapes in many ways. Solids will melt if they are in hot temperatures, and this changes their shape.

energy can neither be created nor we destroy
That energy can only be converted between different forms ~Apex
KE = 1/2mV2
As you see the value of KE is in direct proportion to mass and to the square of velocity. So if either mass or velocity go up, then kinetic energy will go up. The converse is also true.
That the total number of atoms in matter will never change
Answer2:
As I learned it:
Matter can neither be created nor destroyed, only changed in form.
This is/was Newtonian physics. Einstein showed that in nuclear events matter can be changed to energy. And, in general relativity even more complex change can occur.
Water freezing into ice is an example of a phase change from liquid to solid.
