How do you add or subtract energy?
You add or subtract heat. An example is ice turns to water(solid to liquid) then water to stem are water vapor(liquid to gas)
ion
Nothing happens if you combine a fuel and oxygen. However, if you then add a source of energy such as a spark of sufficient power, you get a fire, or, in an enclosed space, an explosion.
All elements become ions when you add or subtract electrons.
nothing happens!

mechanical energy is equal to the kinetic energy + potential energy "gravitational,elastic"
wich one
the result is always even
does how many mean add or subtract
The opposite of add is subtract.
it means to subtract
if you add a thermal energy to a system then it will happens nothing because u dont no anything
when you add thermal energy to matter, the matter starts moving faster.
When you add kinetic energy to a solid the molecules won't move
It stays the same. Only the numerators change.
You arrive at a resultant, the resultant depends on the operation carried out.
