wind resistance, gravitational force, friction.
Bouyancy, pressure, and gravity.
upthrust and gravity
A balloon in a car will probably deflate.
The same way it acts on any other objects. If the forces are balanced, there will be no acceleration.
Momentum, kinetic energy

friction, air resistance and gravity
A balloon in a car will probably deflate.
it puhes and pulls it to make the balloon go one way and the car go the other way
a balloon car works by the air in the balloon.
The same way it acts on any other objects. If the forces are balanced, there will be no acceleration.
Momentum, kinetic energy
if a train is accelerating on a curved track at a constant speed is the train acceeratng
It has lift by having hot air, which rises. Gravity, Lift, and Friction act upon the balloon hovercraft. The friction is a fluid friction known as Air Resistance.
What keep balloon inflated is not the molecular forces but the kinetics energy of the gas molecules made the molecules to bump and create the pressure inside the balloon.
