Hi,thanks foe explanation.

can we say is  check out  like looking something?

Hi, Leila!

"Check up" generally means you're making sure something is okay. If I have a friend who's sick, I might call them to check up on them. You should go to the doctor every six months for a check up, etc.

"Check out" usually means to look at or investigate. I might ask my friend to come and check out a new restaurant with me, or if we see a cool car, I might say "Hey, check it out! What a nice car!"

Here are some example sentences for both cases.

John: Hey, Paul, I was just calling to check up on you. I heard you were ill"

Paul: Yeah, I've got the flu. Thanks for calling.

Joan: I had better call the babysitter and check up on the kids. I want to make sure she put them to bed on time.

Peter: Good idea.

Andrew: "Hey, man, want to see pictures from when I was hiking in Argentina?"

Martin: "Whoa, check out that view! It's beautiful!"

Jonas: "Do you want to come check out this new restaurant with me? It's Thai and it's supposed to be really good."

Mary: Sure, let's go on Saturday.

Hope this was helpful :)

You're welcome!

Basically, yes. If I see something cool, I would point and say "check it out! Isn't that amazing?"
