What makes balloon cars move?
Your balloon car uses jet power to move. The stored air in the balloon pushes through the straw, creating thrust—the force that pushes the car forward. So when air from the balloon moves in one direction, it pushes the car in the opposite direction.
How does a balloon powered vehicle work?
For your balloon-powered car, the contracting balloon pushes the air in the balloon backwards. That means the air in the balloon is pushing the balloon forwards. The balloon is joined to the car, so the car rolls. The motion is nothing to do with pushing on the air behind the car.
How does a balloon car use Newton's second law?

What force must be overcome to make the balloon car move?
In order to get your car to move, you need an unbalanced force. In other words, the force of air coming out of the balloon must overcome the forces acting on the car. You will want to reduce friction and air resistance to help your car move.
What is the hypothesis of a balloon powered car?
This suggests that the more air in the balloon, the faster the car will travel reaction is the air being released out of the balloon and the reaction will be pushing the air. So, the more air the more reaction it will have.
How does a balloon car show Newton's third law?
The gas filled inside the balloon comes out rushing with an immense force which sets the small car in motion. Hence, we see that the force of thrust exerted by the escaping gas initiates the motion of the car. Newton's third law of motion says that every action has an equal and opposite reaction.
How does a balloon car show Newton's 3rd law?
Another way to think about the balloon's movement is to use Newton's third law of motion: For every action there is an equal and opposite reaction. When you inflate a balloon and then release the nozzle, the rubber contracts and pushes the air out the nozzle.
What are the sources of friction on your balloon car?
The ground and other solid surfaces can cause friction, called dry friction, but fluids (liquids and gases) like water and air can also cause frictional forces, called fluid friction.
How does gravity affect a balloon powered car?
As the air flows from the balloon, the energy changes to kinetic energy or the energy of motion. The moving Balloon-Powered Car is using kinetic energy. If you aim your car down a ramp from the top of the ramp, just lifting it up into position adds potential energy thanks to gravity.
How do you make a balloon powered car go far?

How do rubber band powered cars work?
Once the rubber band is released, the polymer chains in the rubber band want to return to their natural, wrinkled state. This releases the rubber band's potential energy, converting it into the kinetic energy that powers your car. Kinetic energy is the energy of motion; any moving object is using kinetic energy.
