thrust and drag, because with out thrust the hot air balloon would not be able to move forward and with out drag it would not be able to stop
When the balloon is hot the density of the air in it decreases and hence the upward thrust on the balloon increases and the balloon moves up and viceversa.
a hot air balloon virtually weighs negative lbs but it would depend on how hot the air is in the balloon.

If there is warm air in the balloon, cooler air makes the balloon rise and if there is cold air in the balloon warmer air makes the balloon fall.
Air= air in balloon solid= balloon and basket
Gravity (weight), Thrust,, Air Resistance (drag), and Lift.
When the balloon is hot the density of the air in it decreases and hence the upward thrust on the balloon increases and the balloon moves up and viceversa.
The thrust is the force moving something forward. The drag is air resistance applying force in the other direction. Drag will increase when an object moves faster because it will hit more molecules (of air, water, whatever) per second. If you apply constant thrust (force) to an object in air (for example an airplane) it will accelerate until the drag is equal to the thrust at which point it stops accelerating but keeps going at the same speed.
Thrust is the produced force of the aircraft that propels the aircraft forward in order to overcome drag. Drag is the natural force of the air that resists the motion of the aircraft.

By overcoming gravity with lift and drag with thrust.

It is thrust, lift, drag and weightthat affect an aircraft's ability to fly. It is thrust that moves the aircraft forward through the air. The thrust overcomes drag and provides (with the wings) lift to overcome weight.
Drag is a force that acts opposite to the direction of movement of an airplane. Drag is mainly caused by air. The other forces that act on the plane while moving in the air are thrust, lift etc..
Thrust - Apex
The 4 main forces of flight are: drag, thrust, lift and weight
Air drag, Rolling resistance, thrust reversing Engines, and wheel brakes
