ELI5: What is the difference between medicine that is chewable and swallow only?

Are swallow only pills less effective if I chewed them?
gpt
Some pills are actually little machines that slowly dispense the medicine. Do *not* chew them. 

Others are slow dissolve to have a timed release of the medicine. Don't chew them either. 

Others are bad for your mouth, but not for your stomach, don't chew them either.

*There* are some that are fine, usually the ones with a line down the middle for chopping in half, but ask your doctor or read the box.
