Stephanie NA commented "Hi there! I was assigned to do a physics project, and we're supposed to build a car that can push at least 500g of rubbish. It has to be made using only mechanical energy, so what kind of car do you think would be the best? Rubber band? Mousetrap?" 

If you have a question it is probably worth reading this video description first because the answer may already be here. To help you find my videos I made two search guides https://youtu.be/ceBSOoOHcgw or https://youtu.be/Zj4UgwkwYRk or checkout my playlists page https://www.youtube.com/user/GrandadIsAnOldMan/playlists?flow=grid&view=1

My instant reaction was to go for rubber band power because assuming you are not restricted on the number of rubber bands you can use, it is easier to control and adjust the power available. I decided to have a go myself and used my Rubber Band Powered Car #8 as the test bed because I designed it to be easily modified for different tasks.
The grip on the back wheels is very important for this project. My helpfile on putting tyres on CDs is probably worth watching. http://www.youtube.com/watch?v=ZnuPnveCbxs&feature=share&list=PLA5a2xPRSrB2v0vxMJyZ9cPweAGx1FK6e&index=8
If the task requires a longer distance to be covered I would suggest making the chassis as long as possible to allow a longer length of rubber band motor to be fitted. My Car #8 allows double the chassis length to be used as it has a pulley at the front for the motor to pass round. It starts at the back, goes forward round the pulley and then back to the back axle.

I have over 2000 videos on YouTube covering a wide range of subjects. To find them follow my search guides https://youtu.be/ceBSOoOHcgw or https://youtu.be/Zj4UgwkwYRk or see my playlists page https://www.youtube.com/user/GrandadIsAnOldMan/playlists?flow=grid&view=1
Generally my projects are for my grandchildren to enjoy. OK, I enjoy them too. If anybody else likes them, that is a bonus. I like to keep my work as simple and basic as possible so that it can be copied easily and improved by anybody who wants to try themselves. I recycle or repurpose items rather than buy new and when I do buy I like to keep it cheap.
