You hit a baseball out of the park and head for first base. Youre excited. The score is tied, and now your team has a chance of getting a winning home run. Then you hear a crash. Oh no! The baseball hit a window in a neighboring house. The glass has a big hole in it, surrounded by a web of cracks see Figure below . The glass has changed. Its been broken into jagged pieces. But the glass is still glass. Breaking the window is an example of a physical change in matter.
