Qual é a diferença entre act e perform ?Podes indicar apenas respostas exemplo.

To put it in simple words, Actors “act” while performing.
Also, “act” means to take action on something.

both are synonyms to each other but can be different.
For example if you’re talking about a cheerleaders performance, they are “performing”. You can’t possibly say they are “acting”.

But if you’re talking about people in a movie of course it’s an “act”, meaning it’s not something natural/they are putting up a front. You’d say that they are “acting”.

If maybe someone you don’t like it’s telling you that they are sorry for something that they did to you but looks like they don’t mean it, they might be putting up an “act”.
You wouldn’t say they are “performing” because it’s not like they had practice.

If you are watching a music theater performance, yes, it is a performance and yes they are acting at the same time. So it’s an “act” and they “perform” at the same time.
Performing = showing a practiced act

Hope that make sense
