So I bought a two meter led strip with 7,2W/m and 30 led/m, so for 2 meters(60 leds) I need 14,4W. I also bought an adapter with output voltage 3-12V, max output current 1500mA and max load 18W. Will the adapter provide sufficient current for the project and what other components (I read about some 12V led strip projects where you need logic level MOSFETS) to make this work?

a link to the strip would help
a link to the adapter would help
Do yourself a favour and please read
How to get the best out of this forum and modify your post accordingly (including necessary documentation of your ask).
I would guess 12V strip, 20mA per led (12 x 0,02 x 30 = 7.2W). Are you sure it's 5V ?
for 2m you need 14.4W under 12V which is 1200mA (60 leds x 20mA) so seems you are within the specs of your adapter but without info, we are in the wild guess territory
if you plan to drive it from an Arduino, yes you need a way to turn it on and off a logic level MOSFET would do.
Please read the first topic telling how to get the best from this forum.
Facts are missing as well as links to the devices.

Sorry it is my first post here, I will add the links in a minute.
Please read that advicing topic first.
At 5V, 14.4W is 2.88A (2880 mA) so your 1500 mA max power supply will not be enough. You should get a 5V supply capable of 3.5A or more.
Mosfets ideally, but power transistors do the trick as well.
