What influences the speed of a toy car?

Answer 1

There are many factors that can influence the speed of a toy car, some of these factors may include:
- aerodynamics: the way the air passes along and around the toy car at high speeds; the more aerodynamic, the higher the speeds it will reach.
- quality of wheels: this may seem a bit odd but the quality and resistance of the toy cars wheels will greatly effects the speed of the car; the smoother the better.
- weight: The amount of weight the toy car has determines the velocity of the car; the lighter it is the quicker it will accelerate and reach higher speeds however heavier cars can reach even greater speeds.
