Question by Rafael_Ferreira · Jul 30, 2017 at 08:00 PM · physics script.velocity force torque

Can I, someway, avoid centripetal force?

I have a circular platform with Rigidbody wich I can rotate using angularVelocity (I cant´t wait for Acceleration. For this reason, I´m not using "realistic" torque) and there´s others Rigidbody objects uppon that platform. I need those objects slide on platform surface, while it leans, but I don´t wanna the centripetal force "repels" the objects, even if it´s physically wrong.

I´ve tryied PhysicMaterials attributes, but nothing worked.

I´m using gravity -10, and objects mass 3.0

Just to clarify, you want the objects on the platform to be spun, but not to fall off?

Sorry but your question couldn't be much more unclear.

Do you talk about 2d or 3d physics? Since use used the tag "physics" and "Rigidbody" we would assume 3d by default.
A platform, by definition, usually refers to a horizontal surface above the surrounding area. Is it just a round disk that is parallel to the ground and rotating like a record (LP) around the up axis?
The centripetal force is a force that points toward the center while the centrifugal force points outwards. The centripetal force is actually responsible for an object to actually stay on a rotating surface. On earth the centripetal force (in relation to the globe) is our gravity. In the case of an object on a spinning disk it's the friction with the object that counteracts the pseudo centrifugal force.

You really should go more into detail when explaining your situation. A drawing, screenshot or video might help. What exact motion do you want to prevent?
