What are the 4 forces involved in making a hot air balloon move?
The four forces are lift, weight (or gravity), thrust, and drag. Lift is generated by the hot air inside the balloon being less dense than the cooler air outside. Weight is the force of gravity pulling the balloon down. Thrust is provided by the burner heating the air inside the balloon. Drag is the resistance caused by the air pushing against the balloon as it moves.
How is a balloon stick on a sweater a scientific investigation?
Using a balloon to generate static electricity and observing it sticking to a sweater can lead to questions about the nature of static electricity, the materials involved, and the forces at play. By systematically altering variables like the type of sweater or the balloon's charge, one can conduct experiments to better understand the phenomenon, making it a scientific investigation.
When making a balloon powered car is it balanced or unbalanced?
When making a balloon-powered car, it is typically designed to be unbalanced. The force of the escaping air from the balloon propels the car forward, creating an imbalance in forces that moves the car. This unbalance allows the car to move in the desired direction.
Why does rubbing a balloon on your sweater allow for the balloon to stick to wall?
Rubbing the balloon on the sweater creates a static charge imbalance on the balloon's surface, making it negatively charged. When brought close to a wall, which is usually neutrally charged, the negative charges on the balloon attract the positive charges in the wall, causing the balloon to stick due to electrostatic forces.
How do you inflate a balloon by using science?
You can inflate a balloon by using the principles of gas expansion. When you blow air into a balloon or fill it with helium, the gas molecules inside the balloon move faster and spread out, causing the balloon to expand and increase in volume. This increase in volume creates pressure inside the balloon, making it appear inflated.

What can you do for a science expo?
Some of the things that can be done for a science expo includes making a film canister rocket and building a super hoop glider. Others include making a balloon rocket.

How science improve way of life?
Science has 75 different fields. Everywhere you look there is science improving your way of life. When a father takes his daughter to school in a vehicle a science is involved there. When a young boy makes his homework in a computer there is science involved there. When a person cooks his meal, there is science involved in the making of the appliances used to cook. everywhere you look, there will be some kind of science involved even when you are only surrounded by nature.

Why does balloon fly?
The hot air inside the balloon expands, making the hot air balloon fly.
What forces are used ina hot air balloon?
Hot air balloons use the force of gravity to descend and the force of buoyancy to ascend. The buoyant force is created by heating the air inside the balloon, making it less dense than the surrounding colder air. The air pressure inside the balloon also plays a role in controlling the altitude of the balloon.
How hot and cold temperature affect air balloon?
Hot temperatures can cause the air inside the balloon to expand, making the balloon rise. Cold temperatures can cause the air inside the balloon to contract, making the balloon descend. Changes in temperature can also affect the buoyancy and stability of the balloon during flight.
