Time in physics animation

Does anyone know how to adjust the speed of things when animating with blender physics?

I’m animating at 24 frames per second and everything feels like it’s one half the speed (really slow).

If I can get it to about twice as fast, it would look more real. Right now everything just looks like it’s in slow motion.

Please let me know.

thanks, in advance.

You have probably got different fps in the Blender Render / Render / Dimensions settings and the Blender Game / World / Physics settings
