well u first get instep n blast that creats a simatelinz curl
No. A cross wind will cause it to curve slightly on the horizontal plane and gravity will make it curve vertically, but you cannot MAKE it curve unless you possess powers of telekinesis.
Parabolic curve
you make one curve. then you make another curve. presto? you have a butt.
It does not. It has a smooth curve. That is called an arc.
In football there is no pitch bases. In football it is hundred yard field that the football players play on.
A parabolic curve is a curve where any point in the curve is an equal distance from two areas. It is an equal distance away from the focus, or fixed point and the fixed straight line, or the directrix.
no you cant
The curve must have a derivative at every point (except its end point).
Three things affect the trajectory of a curve ball: Coriolis effect, gravity and precession AKA spin drift.
The question, as stated, does not make sense.The radius (not raduis) of curvature of a curve at a point is the radius of the arc of a circle which approximates the curve in the immediate vicinity of the point.
If there was no curve to start on not everyone would be running the same distance. The curve has different starting lines on each lane to make sure this is evened out.
Draw the curve on a piece of paper and tape it to the underside of the warp (this is called a cartoon). Then take the shuttle to the curve line and back following the cartoon. Make sure the curve line is wrapped in the weft end. After taking the cloth off the loom, trim the extra warp and serge if desired.
