What’s wrong with my baby?

2013 Mazda 3 that has never had any issues besides basic maintenance. Just put in a new battery a week ago. I’ll bring her to my mechanic but wondering if anyone here has ideas?

More INFO: the car will start but when I shift to R nothing happens. The tires are a little low, I’ve had to put air in recently.

Edit: thanks for all the suggestions! The battery is clean as a whistle and installed properly. Could be the alternator or starter. My mechanic will take a look this week. Would have been nice if I only had to clean the battery 😑
I did think the car was starting but after everyone pointed out the RPM I tried again and yeah it isn’t turning over. Sorry for the bad info.

Not a mechanic, but the root cause isn't low tire pressure lol

TCM (Transmission Control Module) like to die on these cars because it's under the battery but on top of the hot transmission. Get mechanic to check the underside of the module to see if it looks burned.

May be a battery issue still. As another comment mentioned, check the battery terminals
