What's "inertia" mean and when's it used?

Native speaker’s answer

Rebecca

"Inertia" means a tendency to remain unchanged or do nothing. It's also a physics term for when matter exists in an unchanging state or in a uniform motion. Actually, it's not a very common word outside of physics, but it does sound nice and can be quite poetic and meaningful if you use it in relation to things that have remained the way they are or to explain the way you experience everyday life. Ex: It's like there's a state of inertia in this small town. Everything and every day is the same, which is why I prefer big cities. Ex: In an attempt to overcome the inertia of life, I made the impulse decision to buy a boat and start sailing.

When can I use "dude"?
You can use the word "dude" when speaking with friends or people you are close to. "Dude" is a slang English word for a man; a guy. However, this does not have to be gender-specific. Some women will call her female friends dudes. I recommend you only use this with people you are close to. If you use it with someone who is older than you, he or she might take offense. It isn't an offensive word, but it is not very formal with elderly people nor is it formal with people you don't know well. Ex: Dude, where is my car? Ex: Hey dude! What are you up to? Ex: Dude, this sucks! I didn't want to fail the class.
