Preventing a physics body from tumbling

I'm trying to build an app that uses force to push an object.

I"m using the tutorial found here:

http://mobile.tutsplus.com/tutorials/corona/corona-sdk_physics_explosions/

When my "explosion" hits my object, it pushes it but it starts tumbling. I don't mind it turning a little bit.

Any thought about what physics parameters I need to put on a object to limit its spin?

I'm using applyForce now. Would linearImpulse would be better?
