WebDescription. Add an instant force impulse to the rigidbody, using its mass. Apply the impulse force instantly with a single function call. This mode depends on the mass of rigidbody so more force must be applied to push or twist higher-mass objects the same amount as lower-mass objects. This mode is useful for applying forces that happen ...
