How do you build a car that moves without the use of gravity electricity a motor or a person pushing or pulling it?

For the car to start moving, it has to have a force applied to it. Once it is moving, and assuming frictional forces can be ignored, it will continue to move in a straight line.
So, you need something to get it started, and you are not allowed to use gravity, electricity, a motor running on combustible liquids or having someone pushing/pulling it? Mmm.
Is wind power allowed? Put a sail on top of your car and let the unbalanced pressure of the air on each side of the sail provide a net force.
Solar power usess electricity so I guess that's not allowed?
Getting a little extreme, but what about solar pressure? This is the momentum converyed to an object from photons of light. It is the same principle that explains why the tails of comets always point away from the sun. The momentum is so small, it wouldn't get your car moving very fast however!!!

How can a boat move without us pushing pulling or touching it?
wind or moving water
How does a rollercoaster move on its tracks without an engine pulling or pushing ÃŽt?
Going downhill, it's gravity. Going up long grades, there's a chain which grabs onto a hook on the bottom of the lead car.
When a book falls from a shelf to the ground without anyone pushing it Is work is being done on the book?
Work is being done by the force of gravity. When the book falls to the floor, there's a force on it, and the force keeps acting on it as it covers the distance. A force acting through a distance is the definition of work. Maybe there's nobody pushing the book, but the force of gravity is pulling it down, and it's the force of gravity that does the work on the book.
What is the concept of a catapult?
The concept of it is to fling heavy stuff far without a lot of effort of pushing it or pulling it
How do you move a hand made vehicle without pushing or pulling it?
carry it Unless you also hand-made an engine for the vehicle.
What does gravity do for the world?
Gravity is a force of attration.It is a pulling matter.Gravity holds up the earth without gravity we would be having comets every single day ,it holds things in place.
How do you move a car without using gravity or electricity?
pt it on the railroad tracks and wait for a train
What two forces can act on an object without having to actually touch the object?
electricity, magnetism, gravity
Why is gravitation a example of a non contact force?
Because gravity can pull on stuff without touching it. Ocean tides are caused by the Moon's gravity pulling on the water, and that sure isn't touching.
Does gravity affect a hot air balloon?
Yes. Without gravity, a hot air balloon would rise infinitely. You could never return to the ground. Balloons tend to hover more or less. The force of the air pushing up on the balloon and the force of gravity pulling down on the balloon are usually very close to one another. This keeps the balloon at a steady height, unless you heat the air in the balloon, or let it cool.
What does friction have to do with pushing or pulling a wagon?
Friction is necessary to cause the wheels to rotate about the axis of the wagon-- without it the wagon would just slide over the surface.
How can you start a 1995 Nissan maxima without the starter?
if is manual transmission you can, by pushing the car down a hill and suddenly pulling the clutch while the car is on 2nd gear
