Imagine that you are a scientist studying global warming. You’ve been asked to speculate whether we are in the midst of a period of global warming. How could you tell whether
we are in a period of global warming? (Hint: What did you learn about carbon dioxide
levels during the Ice Age?) What effect do you think any environmental change will
have on animals living today? Do you think we should try to stop global warming? If
so, what should we do?

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

the answer is :
