Integral energy is like counting how much energy is in something. It's kind of like counting how many toys you have in your toy box or how many candies are in a jar. But with energy, we use some really fancy math to figure out how much energy is in something.
Imagine you have a ball and you throw it really hard. That ball has energy because it's moving. The faster it's moving, the more energy it has. We can figure out how much energy the ball has by using something called integration. Integration makes us add up all the little bits of energy that make up the whole energy of the ball.
It's kind of like if you have a puzzle with a lot of little pieces. Each piece is important to make the whole picture. If you lose one piece, the picture is not complete. That's what integration does with energy. It adds up all the little bits of energy to make the whole energy.
We use this fancy math to count how much energy is in things like a speeding car or a jumping kangaroo. It helps us understand how much energy we need to power things like our homes or our gadgets.
So, in simple words, integral energy is like counting all the little bits of energy something has to find out how much energy there is in total.
