can slow it using movie editor

Hello again. I am a quite new in blender, so i am making some smashing object using rigid body tools, and set the camera moving around it, but the speed of the same camera and smashing is too much for me. Can I in movie editor slow it, or add some slowmotion and so on? Some tutorials maybe?

my camera is moving very fast…And smashing rigid body object also…why??
