I expacted I can summon Fireball or DragonFireball but it says: cannot summon oběct
but the command was correct

/summon Fireball ~ ~ ~ {Motion:[0.0D,0.0D,0.0D]}

You need the power tag (too(not sure if both at once is required))

try this:
/summon Fireball ~ ~ ~ {Motion:[0.0,0.0,0.0],direction:[0.0,0.0,0.0],ExplosionPower:5}

(you can change ExplosionPower to whatever)
in the future just search for a "how to " video on youtube for help with commands, its much easier to learn what's what that way
