inertia is the energy by which you keep moving. like if you bike like you go down a hill and you keep going that is inertia. kicking in it more or less makes you move but their are things that stop it like friction. would be one when you go down a hill if their are little humps of grass or something this would slow your energy down. and if you had a enough you would stop like we did a project a while back where i had to roll a toy car over some rough surfaces. and we would see wat kind of friction it is like carpet had like tons of friction. also a rug or like just the tile on your kitchen would have inertia and friction the friction works against inertia.

so I have read this part before but I never told you about it this is quite interesting. called rooster earplugs the rooster lets out a cockle doodle do that has 140 decibels. of sound that's loud enough to defend. you that is why the rooster does it in a high place and away from the hens. so he doesn't deafen them also the rooster has these built-in earplugs that totally block up his ear ducts. also he has a lot of hair or something like that in there so it would have to get through that. see even in this stupid animal God has put in these amazing adaptions or something like that other than adaptions.
