How to clear all forces but not the gravity force?

Hello!

I have a object that falls and moves forward. When I clear the forces using
rb.velocity = Vector3.zero; rb.angularVelocity = Vector3.zero;
it drops down very slowly even when I use a large mass. How can I clear every force except the gravity?

If there are no other forces which would make the body fall down, you could use

rb.velocity = new Vector3(0, rb.velocity.y, 0);

If there are other forces, that could make the body fall down, and you want to clear those as well, you should track them, and apply the clearing later on, but this is a bit complicated.

Also, using AddForce() without specifying a ForceMode can lead to continuous velocity-increment through multiple frames, in that case you should consider using ForceMode.Impulse or ForceMode.VelocityChange.
