I pasted an object from another scene but even though there's no keyframes in the timeslider, the object is moving. how can i keep it still?

or sometimes i have an object go linear from key A to key B but for some reason it doesnt move linear and moves to some key C in between. how can i find out whats really going on with teh motion of an object beyond the timeslider?

and finally, sometimes i select an object and the transformation tools come up at the origin of the grid rather than directly at the object. is there a way to fix this or would i need to just recreate the object?

and please dont think i'm asking right after the problems occur. i have tried many ways to figure them out but still perplexed.

tks for your help
