Research It: Mechanical energy is only one of the five forms of energy. Mechanical energy is energy associated with the motion or position of large objects. It is any large object that has to do with gravity too. Every moving object has mechanical energy. Mechanical energy can pull, push, twist, and throw. Machines use mechanical energy and even we need mechanical energy to move. Mechanical energy is just the sum of potential and kinetic energy. Apply It: Mechanical energy is energy associated with the motion or position of large objects. It is any large object that has to do with gravity too. An example of mechanical energy is apples falling from a tree. Also a pullback car is an example of mechanical energy too. Tuning forks are mechanical, but they have some electromagnetic energy too.

Experiment It:

The experiment I chose was where I took three different width rubber bands and strung them on a box. The items I used for this experiment are a rubber band, a box, my hand to string the rubber bands, and my ears to listen. My hypothesis was that the different width rubber bands made different sounds, I will see if I am right with this experiment. First you have to choose different width rubber bands. After that put them on a box. Then just string them with your finger and listen to the different sounds. I wanted to see if the different width rubber bands would make different sounds on the box. In the end the different width rubber bands to make different sounds than each other. It sounds like a chorus. Each rubber band represents a part in the chorus like the altos. The skinny rubber band makes the highest sound like the sopranos. The large width rubber band made the lowest sound like the base. Lastly medium width band makes a sound in between the large and skinny width rubber band like the tuners. This experiment was successful because my hypothesis of the different width rubber bands make different sounds was right.
