Create realistic collision

I want to create a collision of two objects when one of them is weighted much more than the other.
In the example attached the cube is weighted 150 Kg and the sphere only 1 Kg. I expected the cube to barely move after the collision since it weights much more than the sphere but it is not the case. The friction of the plane is set to default and equal to 0.5.
How can it be done? how to make collisions look more realistic in terms of differently weighted objects interaction.


Thank you :slight_smile:
