Hello everyone.
I've got a question that has been bugging me ...
Do bodies have speed limit here on earth?
Like cars, why do they have speed limits? is it because they are made this way for safety or is it because air resistance increases as speed increases?
Not only cars but all bodies in general like jets, can it accelerate non stop ? will air resistance increase and balance it so that it will have a constant speed ( as happens ) ?
And like... if a car moves with a resistance due to air + friction of 100N but is being pushed by a force of 150N, it should accelerate forever, if there was a car with physical capabilities, would it accelerate forever?
Thank you.
