Why can i not understand when to use ke or di correct? Urghh

[Suerte201011]

Ke is when there is motion involved saya pergi ke pasar going to the market where as di is used when objects are stationary di sana over there. Not an amazing explanation as my knowledge of Indonesian is very limited.
Hope I helped, I learned this 2 minutes ago :)
