Need help with Physics

Hey guys, I'm creating a game where u have to jump out of the ground with a worm. I need help in using gravity while the object is out of the ground, but does not drop while in the ground. However, I also need help with the worms movement. I need it to move forward, turn left and right (without drifting). I use the accelerate function but it doesn't work as well as i wanted it to.
