So basically, on an x-y coordinate system, the acceleration vector is in between 0 degrees and 90 degrees pointing north east, and the velocity component is pointing directly east resting on the x-axis. I was wondering what phenomena this represents in real life and I was also wondering, with the velocity pointing east resting on the x-axis for the next cases, what would it look like when the acceleration is pointing northwest, southwest, and south east. Here are examples of what I know so far. When the acceleration vector is pointing directly west resting on the -x-axis, and when the velocity is pointing directly east resting on the +x-axis the speed of the object is slowing down. The other example is when the acceleration vector is pointing directly north resting on the +y-axis and when the velocity vector is pointing to the east resting on the +x-axis velocity is not increasing and is constant. For my question I stated above, I know that we can break them apart into vector components i and j; however, I don't understand what that means in real life and what is going on.
