Newer models are made. The parts become worn, upkeep may not be optimal. It is primarily a machine and newer machines are designed and parts become obsolete.
The engine supplies the rotational force that ultimately makes the car go down the road.
It cuts down on the wind resistance of the car behind it, which makes that car push the other car faster than the one by itself. Because the one by itself isn't getting a push behind and its not pushed by another car which slows it down!
i always assumed so. used car salesman dont brag about it being a 1 owner car for nothing
If the toy car's ramp is on 45 degrees and if the toy car is put on some weight, the toy car will go faster because it goes faster, which makes the car go further.
negligable effects if ....all other factors exact. same
The sun doesn't go down We go round.
Reverse
A toy car will go slow down a ramp due to gravity, which pulls the car downwards. Other factors like friction with the ramp and air resistance may also contribute to the slower speed. The steeper the ramp, the faster the car will go due to gravity pulling it more strongly.
To most people that would be an improvement but someone that wants an all numbers matching car it would decrease the value to them.
My car idles really high and wont go down and it will stall if I push on the gas!!
