Sonstiges » motion graphics error??

Hello,
I am new in this field and i want to know about this field. I read some magazines,books.I want to stand in this field. Motion graphics is where animation and graphic design meet. Motion graphics and animation can definitely be interchangeable in some places. Understanding basic principles of each discipline will make you a better motion designer. is this right definition? I went through many resources and also checked Business Motion Graphics Example but did not find the right solution. Please help me out.

Any help will be appreciated.
Thank you.
