Question

I NEED HELP HURRY??!! Pretend you are in a world with no friction or air resistance. You are on your bicycle at the top of a small hill. You kick off and without pedaling, you roll down the hill. How far will you go without pedaling in this pretend world? How does it compare with how far you might go in the real world? If there is a difference between the two worlds, why is this so? Explain as precisely as you can, using the law of conservation of energy in your explanation.
​

Answer 1

Answer:

you will go no where as far as you wish because there is no air resistance or friction, causing you to not stop.  In the real world, you would stop a little bit after you got done with the hill because you have friction and air Resistance to bring you to a stop.  There is a huge difference because in real life, there is a lot of friction and air resistance in the real world, which will eventually bring someone to a stop no matter how fast they are going.  

Answer 2

Answer: If there was no friction you would just keep going and going and going on there is no stop. Matter in fact without friction we would not be able to walk as humns nor any animal for that fact.  The only way to not move is to stay rooted like a tree.
