Reproduction steps:
1. Open the attached project;
2. Open the scene 'TestPhys';
3. Ensure 'Impulse' on TestController ('Sphere' gameobject) is unchecked;
4. Enter in the Play mode;
5. Observe how the sphere rotates and moves until coming to a stop;
6. Stop Play mode;
7. Set "Impulse" on the TestController ('Sphere' gameobject) to true;
8. Enter in the Play mode;
9. Observe how the sphere rotates and moves;

Expected result: 'Sphere' should stop after function 'AddForceAtPosition' end (expected_result.gif).
Actual result: 'Sphere' vibrates and a little bit moves (actual_result.gif).

Note: When "IsKinematic" quickly turn on and then off, 'Sphere' moves correctly.
