Based on what you have read, what would be another example of kinetic energy? A hammer hanging from a peg
Ahammer resting on a table
A hammer falling off a table
A hammer lying on a board

its a  hammer falling off a table

Explanation:

i think its cause the gravitational energy gets converted to kinetic energy when its falling down

gold is my favorite solid.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
