New Android App Encourages Users To Throw Device As High As Possible 156

Uhhh, no. The snap of sending the yoyo to the end of the string is a high acceleration, but while it is spinning on the ground it is feeling 1G. It is that 1G that keeps the tiny amount of friction from the string from catching the hub and ending the trick. If the yoyo wasn't pulling against the string it would easily catch and strart to wind back up.

The phone at the end of the string is subjected to much more than 1G as you spin it around. It is that force that is keeping the phone from simply dangling at the end of the string. Why do you think you need to pull back on the string so hard if there is "0g" on the phone at the other end? That pull you exert is the "equal and opposite" part of the laws of motion. It is the same principle that makes centrifuges work; the rotation of the centrifuge creates HIGHER forces (more g's) on the thing being sp

Thank you for clearing that up.

Re: (Score:2)
The rotation of the yoyo is not why there is 1g during "walk the dog". There is 1g experienced by the yoyo because it is subject to the earth's gravitational field and is being prevented from accelerating downward by the carpet/floor it is in contact with. If you simply hang a phone from a piece of string, it will experience 1g because the string will be pulling upwards to keep it from falling to the floor.

Sorry, you fail physics. As someone has already pointed out, once the phone leaves your hand, and if we neglect air resistance (which would probably be negligible), then the phone will measure *no* acceleration at all at any point during its rise and fall. Determining how high it was thrown is likely done simply by knowing how long it was in free fall, and how strong the Earth's gravitational field is.

When anything falls to Earth under gravity it is accelerating at ~9.8m/s downwards. The reason why you are weightless during free fall is because you are not resisting the acceleration.

You know, I thought about that, but two problems: model rocket motors are not very powerful. Your standard D12 motor is designed to output 12N of thrust. Your .25kg phone* + .25kg rocket** is being pulled to the earth with a force of (.5 * 9.8) = 4.9N. So you get a net upward thrust of 7.1N for right about 1.5s. For the hypothetical half-kilo load you get 14.2 m/s^2 for 1.5s. This gives you a max vertical distance (discounting wind resistance and suchlike) of d = 1/2(14.2)*((1.5)^2) = 7.1 * 2.25 = 15.9

Sure, you could probably thrown your phone 45 feet or more into the air - but could you catch it? Would you dare, considering how much a replacement might cost?
But, you could launch it - and allow it to be carried down by a parachute.
And you might use 2 or more motors. If you're going to such lengths to cheat - why not cheat it up right?

Thank you for the ballistics calculations. I think that the phone throwing app would register a much lower throw than your calculations predict. Presumably the app measures the time of 0g acceleration. In that case, this would start at the end of boost, ie when the rocket motor burns out and then end when the parachute opens (sudden jolt followed by constant,1g, fall to earth).
