Conservation of Energy

Conservation of Energy

By Braden Sparks

It can only be transferred back and forth between types of Kinetic and Potential energies.

​

Energy cannot be created nor destroyed

​

However much energy there was since the Big Bang, is exactly how much energy there is in the universe today.

​

Energy does not randomly appear or disappear. ​

​

Energy cannot be created nor destroyed

​

The Law of Conservation of Energy

Energy is not created nor destroyed. Just transferred.

​Here's an example:

​Atoms in the Sun's core fuse together and release light energy.

The light hits plants. Plants turn that into chemical energy.​

​Humans can eat those plants for energy (chemical energy). Or we can light it on fire! Which is the chemical energy being converted to thermal energy.
