Can you explain the reason behind the difference in property names:
$(elem).css('padding-top')
compared to
$(elem).css('marginTop')
? Wouldn't it make more sense if we use:
$(elem).css('margin-top')
instead?

You have the option to utilize either the "camelCase" or "hyphen-separated" form of properties. Both methods are effective. Refer to the jQuery documentation on .css() for more details:
jQuery comprehends and processes the CSS and DOM structure of multi-word properties with equal proficiency. For instance, jQuery can accurately interpret and retrieve values for both
.css('background-color')and.css('backgroundColor').
In this way, all of the provided examples would function properly:
$(elem).css('marginTop')
$(elem).css('margin-top')
$(elem).css('paddingTop')
$(elem).css('padding-top')
There are two perspectives to consider: how CSS interprets it and how you can manipulate it using JavaScript. In CSS, the syntax looks like this:
#element {margin-top: ...;}
On the other hand, in JavaScript, you would access it like this:
document.getElementById('element').style.marginTop
Interestingly, both the JavaScript method and the CSS method work when passed to the css() function.
