Change the rigidbody's velocity, using its mass.

This mode depends on the mass of rigidbody. Therefore more force must be applied to push or twist higher-mass objects the same amount as lower-mass objects. This mode is more like a velocity than an acceleration. In this mode, the unit of the force parameter is applied to the rigidbody as mass*distance/time
