k can someone answer this for me gravty can not be broken so tell me how can a roll over?

Think of a car traveling at 90 mph up a ramp. When it gets to the end of the ramp all four wheels leave the ground and the whole car continues upward. Is gravity broken? No, it's just that the velocity of the car upward has more force than gravity trying to pull it down. Of course it will pull it down as soon as the upward momentum decreases enough.\n\nAnother example. The Shuttle orbits around Earth even though gravity is still there and as strong as ever. Again there are two forces at work on the Shuttle -- gravity is pulling downward while at the same time the Shuttle's speed is trying to hurl it off into space. The two forces aren't cancelled or "broken," they're just balanced so that neither completely gains control of the Shuttle.

Flip the entire thing over

Over the top. You can just put your hand on top of the roll and give it a good whack and the sheets just come flying off. Actually, I think it ought to be a crime to reverse the roll. The FBI could install cameras in all the bathrooms to make sure everyone is doing it correctly. For all I know maybe they are.

Probably it's so you can roll over without falling off it and waking up.

Ask Granma what she thinks. If she has busted your terlet, it probably is not the first on she broke. (lol! I like this question)

Just work with what you have. You keep messing around trying to make it bigger and you're gonna break it!

actually, it can! If you understand physics, the website below has proof. (but I dont know how hard you threw it.)

mmmmmmmmmmmmmmmm...................it will break?

Good question,but remember it's a nursery rhyme...You have to associate humpty with something that is breakable and non-repairable..Just happened to be an egg,,Stay sweet..

Since the piece of cheese is at rest. and no net force is acting. by Newton's First Law of Motion, it would continue in its initial 'state of motion'  which is rest here (since it was initially at rest) ....all other choices would violate the law!. got it dear!

I'm afraid I can't do that. It'll burn up and disintegrate before it even gets half-way down to you. :-P

It's me again, Dhinesh,your classmate.\nrolling frictin is the friction caused due to rolling. it opposes rolling & it acts on a single point as there is a single pt. which has contact with surface

This question sounds like your teacher/ta/whoever wants you to make 3 assumptions (or they already did and you just didnt mention it):\nThey have the same mass (otherwise he would have to specify the masses of each)\nAir resistance is negligible (pretty common)\nThey all roll without slipping (otherwise they all get to the bottom together)\n\nIf you make these assumptions, the order is based on their respective moments of inertia about the center.  They each move downward at a speed based on their rotation, so the order they reach the bottom will be smallest rotational inertia first. Sphere, disk, ring.

The rotational energy you impart to the object when spinning overcomes the force of gravity that would topple a stationary object.  \n\nA total layman's explanation:\n\nA perfect stationary top perfectly balanced will not fall over.  In real life though,it's impossible to perfectly balance a top.  It's shape practically guarantees that its center of gravity will not be directly over the balance point for any practical length of time.  Imperfections in the material will cause a slightly uneven weight distribution, air currents will introduce a small force, and mechanical vibrations will be transmitted through the medium the top rests on.  The upshot of all this is that as soon as the center of mass is no longer over the resting point, gravity is going to pull the top over.  \n\nNow gravity has an acceleration of 32 feet per second squared (if I remember my ancient high school course correctly).  It can only topple the top at a specific speed.  If you spin the top fast enough, any side that gravity tries to "pull down" will translate around so quickly that it literally has no time to fall.  If you were standing on a planet with a much higher gravity, you'd have to spin the top far faster to achieve stability, and if you were on the moon, it would spin for a much longer time. Eventually, however, the top starts to slow and the tip will inscribe little circles.  That action is called "precession".  And of course, eventually the thing drops to the table and the game is all up once it slows enough.\n\nAgain, that's a layman's view of how it works.  Some college physics major is probably going to come in here and make my answer look really foolish.

mass in motion stays in motion unless disrupted by another force!

Bacause Nothing is impossible. Just because you can't make it possible, doesn't mean that someone somewhere sometime can't make it possible.

This kinda thing is impossible...
