Use your hand to make la... so easy....
Glue a balloon to a little toy car. Blow up the balloon, without tying the end. Set the car with balloon on the ground and watch the car be propelled by the air coming out of the balloon for about 15 feet.
A heavier toy car is better to go down a ramp and make a jump better than a light car because the heavier the toy car is, the faster gravity will force it to roll down the ramp, and with all its speed, be able to make the jump. Of course, you wouldn't want to make the toy car so heavy so that it barely or doesn't move at all. Just like drops of water when it's raining outside and a few drops hit your window. The heavier drops drip off faster than the smaller ones, and that goes the same with cars, too.
I'll accept that. What's your question ?
Yes. If it is heavy it will go slower than a light toy car, if it is light it will movefaster than a heavier car.
You could put a small motor in it.
Assuming you mean a toy car, build a "mouse trap" car and use your imagination.
probably in china, 500bc, toy powered by steam turbine
because the little toy car doesn't move by its self
for something to move it needs force . force can be energy.force equals mass and acellaration.basically,mass needs force to move. if you want to make a self propelled toy , you either need to make a chassis or frame for the toy.then you need to add wheels because for it to be self propelled,it needs to be on an inclined plane.that way gravity can pull it down.if you want it to be a flying self propelled plane it needs to be on a very large slope,it needs to have a frame ,a body,a propeller or two,large wings,and the slope needs to have a ramp.for it to be a car it needs wheels,a chassis,and a body.it needs to be on a slope without a ramp.for a self propelled boat,you need a frame,something heavy to create momentum like a metal wheel inside one of the toys that you push and they keep on going.you need some thing to catch the waves and make the metal wheel spin.then you need something like the things on the back of old steamboats. good luck!
a battery and a toy car..........................
poo your self
NO
Rubber band car
There are many toy car companies that make toy car garages suitable for younger children. Some of these companies include Matchbox, Hotwheels, and Little Tikes.
you can make a toy car move with a ballon and pump by blowing balloon up and leting the pump go
you push it
