In summary, the conversation is about seeking help for a Physics Portfolio on hovercrafts. The topics that need to be covered are the present, main and secondary physics principles, related items, and the future. The person is also looking for websites to gather more information and citations. Additionally, they mention the importance of understanding air pressure and friction in hovercrafts. The main physics principles to be discussed are Newtonian mechanics, specifically Newton's second and third laws. The secondary principles include the relationship between pressure and force, as well as the cushion of air generated by the hovercraft's work. For further information, the person suggests googling hovercrafts.

I need whatever help I can get on the following topics about a hover-craft for a Phyics Portfolio due in 2 weeks:
1. The Present
2. Main Physics Principle/Concept
3.Secondary Physics Principle/Concept
4. Related Items
5. The Future

It would really help if you could give me websites where I can get more information, so it can be cited... Thanks for the help.

if you are doing calculations for this project, you might want to investigate the air pressure inside the hovercraft. this is seen through P=force/area. use this equation to discuss how surface area relates to the amount of weight that a hovercraft can hold up, or how the pressure of the air inside the hovercraft changes when more weight is added.

furthermore, learn about how hovercrafts reduce friction.

As far as the main physics go, you need to understand Newtonian mechanics. Newton's second and third laws. Secondary principles, are just as important, that has to do with presssufre use erjkism's formula P=F/A, and the cushion of air that hover craft generates through work. For related and future items just google hover craft.
 

1. What is a hovercraft and how does it work?

A hovercraft is a vehicle that is able to travel over both land and water by using a cushion of air to lift and support it. It works by using a fan or impeller to force air under the vehicle, creating a high-pressure area that lifts the hovercraft off the ground. The air then exits through vents around the edges, creating a cushion that reduces friction and allows the hovercraft to move forward.

2. What are the main principles behind hovercraft physics?

The main principles behind hovercraft physics include the Bernoulli's principle, which states that the pressure of a fluid decreases as its speed increases, and Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. These principles work together to create the cushion of air that allows the hovercraft to float and move forward.

3. What are the secondary principles involved in hovercraft physics?

Secondary principles involved in hovercraft physics include lift, drag, and stability. Lift is the force that counteracts the weight of the hovercraft and allows it to stay afloat. Drag is the resistance caused by air pushing against the hovercraft's surface, and stability is the ability of the hovercraft to maintain its balance and control its movements.

4. What are some related items that affect hovercraft physics?

Some related items that affect hovercraft physics include the weight of the hovercraft, the size and shape of the hull, the type and power of the engine, and the air pressure and humidity of the surrounding environment. Other factors that can affect hovercraft performance include wind speed and direction, water conditions, and the skill of the operator.

5. How do engineers apply hovercraft physics to design and improve hovercrafts?

Engineers use their understanding of hovercraft physics to design and improve hovercrafts by optimizing the shape and size of the hull for better lift and stability, selecting the appropriate engine and fan size for maximum air flow, and implementing control systems to manage air pressure and direction. They also consider various external factors and use computer simulations and testing to fine-tune their designs for optimal performance.
