How Can I Maximize Efficiency in a 1 Joule Vehicle Project?

[xale52791]

Alright. I have a physics project due in about 10 days and I am not quite sure how to go about it. I have to make a "vehicle" move as efficiently as possible. I can only use 1 Joule of potentional gravitational energy per the equation mgh. The only specifications of the vehicle are that it is safe to its surrounding and the people watching and that it has at least 2 wheels on the ground at all times. I can either make it move using an inelastic collision (that way the weight of the car isn't counted into mgh) or i can put the car on a ramp and have its vertical height and mass count into the equation.

I think that i should just drop the car because not all the work will be conserved into force during an inelastic collision. The simplest way to do it would be a 100g car and the track 1m high. I don't know what the best way to do it is, whith more mass and less hight or the other way around.

My idea is to use a maglev type of thing with 2 guidewheels to keep it straight.

Any help is much appreciated!

probably not going to have time to do a maglev, so now I am thinkin just something really light with a longer drop and very large wheels

Hi there,

Thank you for sharing your project and asking for help. It seems like you have a good understanding of the requirements and are considering different options for achieving maximum efficiency. Here are a few suggestions that may help you with your project:

1. Start by researching and understanding the concept of Joule efficiency. This will help you understand the factors that affect it and how to optimize it.

2. Consider using a combination of methods to achieve maximum efficiency. For example, you could use a combination of an inelastic collision and a ramp to transfer the potential energy into kinetic energy.

3. Experiment with different masses and heights to see which combination gives the best results. You could also try adding additional features such as aerodynamic designs to reduce air resistance and increase efficiency.

4. As for your idea of using a maglev type of thing with 2 guide wheels, it could be a good option but make sure to do some research and calculations to ensure it will work effectively within the given specifications.

5. Don't be afraid to ask for help or advice from your teacher or classmates. They may have some useful insights or suggestions that could help you improve your project.

Overall, the key to achieving maximum efficiency in your project is to carefully plan and experiment with different options. Good luck with your project and I hope these suggestions help you in some way.
