Pogeymans stuff

Arcanine is 340 pounds. Charizard is 188.

LL Topic. One of the more interesting posts on there:

Two of Scyther's Pokedex entries:
It slashes through grass with its sharp scythes, moving too fast for the human eye to track.

With ninja-like agility and speed, it can created the illusion that there is more than one.

Scyther must be lying in the ground in order to encircle his enemies at such a speed.



PROOF:

The human eye sees around 20 "frames" a second. For the human eye to see afterimages, that something must be seen in many places - each not moving - in consecutive "frames". Thus, Scyther must move its own width in 0.05 of a second.

Scyther is about 1.5m long and high. Thus, it must move 1.5m every 0.05 seconds, or 30m/s, which is 108km/h or 72mph. Assuming it wanted to encircle its enemy with a complete set of believable afterimages, that circle would have to be, at most, 30 metres in circumference so Scyther can make it back to the start in time to stop that afterimage from disappearing from the person's sight. The radius of such a circle would be ~5m. Therefore, the centripetal force required to keep it moving in a circle is,

F = mv^2/r, where m=mass (55.8kg), v=velocity(30m/s), and r=radius of the circle (10m)

Thus, F = 55.8*30^2/5 = 10044 N.

To prevent from tumbling off in a straight line at 30m/s, Scyther must be leaning at an angle that makes the resultant force of its weight (~508N) and its centripetal force (10044N) travel through its centre of gravity. To find the angle with the ground,

angle = 1/tan(508/10044) = ~2.9 degrees. Practically horizontal.

This is also completely negating the fact that grass or dirt doesn't have anywhere near a high enough coefficient of friction to allow Scyther's feet make it run in a circle that tight at that speed.

To find a more reasonable angle - say, 60 degrees, so he won't be eating dirt at 108 km/h - for Scyther to be leaning forward whilst encircling an enemy, the radius of the circle must be changed.

To find the centripetal force Scyther must have to need to lean at an angle of 60 degrees,

centripetal force = 55.8/tan(60) = ~32.2N

Now to find the radius required,

F = mv^2/r
r = mv^2/F
r = 55.8*30^2/32.2 = ~1559.6m

Therefore, Scyther must be traveling in a 1.5km radius circle in order to encircle his enemy. Though it's not likely to work that well, given the first set of afterimages would disappear when Scyther is 2/100ths of the way through one complete encirclement.
