describe why energy isnt really lost due to friction?

Remember your conservation of energy. It cannot be created or destroyed. In the case of friction, it appears that an object loses energy as it slows down. While its true that the kinetic energy of the object is dissipating, it is being converted into heat and sound energy. If you rub your hands together you can feel this heat being generated. If you slide something across a table or floor, you will likely hear some sort of noise as well. These are both forms of energy that are being converted from kinetic energy by friction.

The energy that results from friction is dissipated as heat energy rather than being lost.

Hello tina, really energy is lost due to friction. Energy is to be spent to do work against friction

First law of thermodynamics - energy is conserved.

But it might as well be lost if it's turned into low-level heat - you can't do anything with it except keep your house warm. Energy lost in stopping your car with brake pads can't be recovered.

It becomes heat and then dissipates into the air.
