Animation's performance

Does animation inclusion affects performance – reduces performance?

having multiple skinned animations running will indeed affect performance. It’s much less CPU intense to have a non animated object as opposed to an animated object.

But what if we have to do the physics instead of animation for achieving the same result?
what’s the trade-off in that case?

Physics is always more expensive than canned animations simply because one is replaying ( and potentially mixing) pre-recorded data while other is recalculating everything from scratch on every frame.

Thanks warmi, thought so to be the case logically
