Throwing a javelin at the optimal angle.
Throwing a javeline at the optimal angle is throwing a javelin at the angle which the air flows efficiently
around the javeline.The center of pressure is the aerodynamic force of drag and lift on the javelin.before
the 1986 change in javelins , some of the best throwers in the world would throw the javelin with as little as
30 degree angle but greater speed because they were able to hold onto the javelin for longer , producing
more force . Good throwers still use this method but the most commen method is releasing the javelin at
about a 40 degree angles,causing a longer flight for the javelin.

360 degrees
This is true when the object lands at the same height as it was thrown, but not necessarity if the two are different. You can think of the motion in two parts; it moves upward and it moves sideways. If you throw it at a high angle, it won't have much of the sideways motion and won't travel far. If you throw it at a low angle, you won't have much upward motion and it will hit the ground before travelling too far.

obtuse angle
That's a reflex angle. 0 to <90 Acute angle 90 Right angle >90 to <180 Obtuse angle 180 Straight angle >180 to <360 Reflex angle 360 called Full circle
just an angle, like any other angle.
