NO. Energy neither be created nor be destroyed but one type of energy can be transformed into another - Law of conservation of energy. The cancellation of energy is apparent. Example. If the conductance of electricity through a conductor is restricted by a resistor, we can feel 'nil' conductance of electricity through it. This will give the notion that the electricity conductance is stopped. But, really, the electric energy is converted into heat energy. This is called transformation of energy. Thus energy cannot be destroyed. Another example, Acid-Base neutralisation. This is an exothermic reation. Here lot of energy is released. But in notion, we feel that the acid cancels the base.

One of the fundamental laws of physics is that energy can neither be created or destroyed.
For example, you throw a ball of clay at a brick wall. It has kinetic energy.
It hits the wall and sticks.
It makes a noise. This is wave energy. It also deforms. When it deforms, It will warm up (almost imperceptibly), which is thermal energy. It may eventually fall off, and if it's high up, it will have potential energy that will be used when it falls. It will also transfer momentum (more kinetic e) into the wall, which will probably be absorbed unless it's a very, very, very big ball of clay. The energy transferred to the wall, will dissipate from the wall in various ways of energy transfer.
For what it's worth, I've dated more than one gal where our energies totally cancelled, so yes, energy can cancel if you get outside of physics with it.

They change form, and at that particular time for that particular object animate or not that form of energy is not available but has the potential to be restored ( as long as not to much of any one form of energy is put back into that object to change it physical appearance, because if that happens that form of energy in that exact amount can never be returned or duplicated to that exact degree).

Sometimes yes, sound waves, if they meet when one is at it's peak and the other at it's trough, will cancel each other out. They use this to deaden sounds in airplanes and cars and things sometimes. The sound wave is a form of energy.

Energy, kinetic or potential don't cancel they just transfer.

energy is not expressed in terms of +/- with sense of direction.
hence energy cannot cancel against each other.
energy expresses the quantum of work or work content in it.
