I need to make a motor powered boat for my physics class and I need a nice working propeller. The boat is probably the size of a shampoo bottle. I need to make a propeller but I don’t know what I should make it out of or how to. Hopefully anyone... Read More

In High school physics, we have a project where in groups of 6 people, we build a boat using whatever we want. We have a month to build a boat that can carry two people and can race against other boats from a different school. Is it better to build a... Read More

I dont have much to work with, only 8 ft long pieces, 10 pieces, 1/2 inch wide, 1/4 inch thick of plywood. We can use paper, glue, and tape. Help! Posted by beatlebryce  Read More Ø

Recently I built a cardboard boat for my physics class. Part of the report asks for real-world applications of the physics used in building a cardboard boat, or the applications of the knowledge learned in general. What are some applications related to... Read More

I’ve read that the Toyota Prius uses a combustion engine to charge the battery for its electric engine, but is it possible to use the motion of the cars wheels, once it is running, to charge the battery instead. It would require a lot less gasoline... Read More

I’m studying for a physics exam and going through the problems at the end of the chapter. The question is: The front wheels located far out in front of the racing vehicle help to keep the vehicle from nosing upward when it accelerates. What physics... Read More

In my physics class I need to build a boat made of a square sheet of tin foil and 15 popsicle sticks. I can use a glue gun to glue the popsicle sticks to the tin foil but the tin foil must be in one piece. What is the best way to build this? I need a... Read More
