a surface with an air intake
When toy cars go down a steep hill they pick up momentum. Which makes them go faster so a car on a steeper hill will go faster then one on a flat surface.
Because the red that they use makes our blood flow faster somehow and makes them look faster, that is why people say ferraries that are red go faster.
its called drafting
The fastest way is to use compressed air to blow water out of the ballast tanks. This makes the submarine buoyant and it raises to the surface. The faster it is done the faster the sub will go up.
yes it goes much faster
they go faster now.
It's better for the environment and makes cars go faster than diesel. Diesel engines are however, simpler.
The lift and thrust force makes an airplane go faster.
Depends faster cars are not that safe so go for bigger but not to fast
No, drag actually slows the object down but thrust makes it go faster.
it makes it go faster and prevents viruses
the smoother the surface the faster you go the bumper the surface the slower you go. smooth surface less effort to go farther and vice - versa
