This weekend I did a lot of things that involve energy. On Saturday I ran on my treadmill. This is mechanical energy. Another thing I did this weekend that involves energy is turning on the stove when I was helping my Mom cook dinner. Turning on a stove is thermal energy, which is a type of kinetic energy. When I ate my food during dinner I was breaking chemical bonds in the food and releasing chemical energy. When I turned the toaster it used energy. When I plugged the toaster in the outlet it turned into thermal energy heating up the bread. I used a lot of energy this weekend.
