The energy from the ball dropping didn't disappear. My reason is because of the law of conservation of energy. According to the law, energy cannot be created or destroyed. So my friend was incorrect. Energy may not be able to be created or destroyed but it can be transferred. So when the ball reached the surface of the floor, it transferred some it's energy. This caused some of it's amount of energy to be reduced, making it stop bouncing. So in conclusion, the energy didn't disappear it was transferred.

The nail head gets warm because of the kinetic and thermal energy associated with the hammer coming down upon it. The formula for kinetic energy is mv2 divided by 2. So when you bring the hammer down upon the nail, you have your kinetic energy. When the hammer hits the nail, the molecules in the nail move faster. When the molecules in the nail move faster the temperature increases. Thus causing the thermal energy creating the temperature to increase. So in conclusion, that is the process of the hammer and the nail.

Technology in Science

I like science because if I become the doctor when I grow up, at least I've learned a few things. ( A doctor is one of the many of my possibilities.) I like using the computers during science because it helps me get a better feel with the computers and how they work. So far, we've learned about the different types of energy and the formulas. We've also learned a little more on the computers.
