I see this Is your homework Grampa!!!!
Oops, I'll probably get another bad rating for this one.
 Are you going to aeronautical school, Grandpa?
Aren't you going to retire soon?
Anyway, I think you are right. Thrust and lift.

Husband thinks it's gravity and resistance.(drag) But, he was a helicopter crew chief, so don't rely on that. lol.

I would guess gravity and lift.
 
I'm sure someone will let me know if I am wrong.

yeah that was what i was thinking but surely if it was that the forces would be equal so the plane wouldn't go up. Maybe it's thrust and lift as the plane is going forwards as well as up

So, at take off thrust and lift are overcoming gravity and drag or friction. I think I get it, Thanks

Excellent deduction, jb185. Five stars for you.

Why only two?
There are four significant forces acting on a plane at take off (and flight):

  1. Thrust

  2. Friction (drag)

  3. Gravity

  4. Lift (dependant on velocity of air over the airfoil).

He's asking for the 2 main forces at take off...thrust and lift are overcoming drag and weight...they would be the 2 main forces at take off...I think.
