What forces are used when a toy car goes down a ramp?
I am not sure what you mean by "forces used" as there are many forces at work on every object constantly. However, in this case the main forces are gravity friction and air pressure as well as the main force of the car =mass times its acceleration or speed.

the person that wrote this well clearly did not take science as a degree!! what they mean by 'forces used' they mean 'what forces are there when a toy car goes down a ramp' some may get this other may not. the forces used are gravity friction and air pressure. some may say weight is also included in this advent. the mass of the car is normally included in the gravity or weight. thank you!!
