Hello Henrique,

Is the behavior of the sphere set to flexible or rigid? Please click on the part and look in the details.  If not, can you double check the material units used for the bodies.  I have seen where a mistype of MPa vs Pa cause similar issues.  Also, even if the materials are correct, double check that the body has that material assigned. Thank you.

Regards,
Sean
