Can someone please explain this to me?
i recently heard of the law of conservation of energy. To me this law makes no sense since it states that energy cannot be created or destroyed. Okay ill admit, im not so good at science but can anybody please explain all this in a simple manner that ill understand?

what do you mean, like a oil tanker colliding with a sedan head on?
The huge forward force of the tanker would transfer to the sedan, while the sedan transferrs its smaller forward force to the tanker. The tanker recives the smaller force and therefore slows down a bit. However, the huge force of the tanker would cause the forward momentum of the sedan to decrease, causing stress and finally smashing the sedan to a pulp.
(I think I was explaining conservation of matter... slightly related)
But not really, its just transfered...
Take a car crash.
the first car car hits another one (parked),
the first car stops, but the other one goes flying down the street.
Thats because the first car transfered all its energy into the other car.

what about plasma cutters? is that not matter they are creating? or blow torches?
Torches take energy by destroying some molecules (O,C...). Fire can't appear in vacuum where it has no sourse of energy.
After destruction of the molecules the free energe transferes into the light and warmness.

Energy, like matter, cannot be created or destroyed, only transferred between objects. Like for example, with matter, the food a person eats is converted into muscle, organs, bones and so forth, then when they die, the matter from their bodies is used up by plants and etc... Or when you burn something, it doesn't go away forever, it's just broken down partially. A lot of times it looks like matter or energy "disappears," but it really doesn't, it just goes somewhere else.

yet they havent said anything wether it can dissipate or not or be destroyed. i mean think about...theoretically if a greater or equal force collided with another wouldnt it be destroyed or eventually come to a stop?
Yes, but only here on Earth, where we have friction. Friction is inescapable except in a vacuum. In a vacuum it would keep going forever. Newton's Laws, man. 😉
