Questions about physics_dt

Hi, I am a new baby to Issac Sim.

May I know what is the definition of physics_dt=0.1that is used in time stepping?
I noticed that this parameter actually can change the behaviour of the robot, like the velocities and even the movement of robots.

For example, with the same command, moving forward 3m/s, in different physics_dt, the robot behaved slightly differently. Why?

Thank you.
