Coliders and Kinematics

I made a simple game with a player (A sphere with box colider, and gravity) and falling platforms (Another rigidbody, without gravity but runs constantly down by script)

The problem is that when the player is in the platform, he does little jumps automaticaly, something like a bounce (But is not), i saw in forums that could be because of kinematics

Can someone explain me how can i avoid that “Littlejumps”?

Try moving the platform down during FixedUpdate() instead of Update().
