ok change of question: what is the maximum angle of projection of a projectile so that it will clear the side of the earth on its way down, this gets annoying as the magnitude of the gravity force change as you get further from the earth and the direction of the force is always to the centre of...
what is the range of angle for launching a projectile into orbit?
if you say angle is irrelevent: read below; else don't bother reading it
i posted an earlier question similar where i wanted to find out the direction of escape velocity and was told direction is irrelevent, so i assumed since...
Does relativity only apply to linear motion?
what about relativistic speed objects that constantly change direction like circular motion or objects travel along a linear path but constantly change their velocity like a vibrating object (simple harmonic motion).
...Doh thought about this on the...
i have no idea what i'll get so can someone try give me an estimate on the way i'm going?
my ranks are around:
english adv - 110/180
maths ext 1 - 15/80
math ext 2 - 1/20
physics - 20/50
software design - 3/12
my school rank is around 40 (i'm going on the assumption my year is worse than...
Ok i know its stupid of me not know this but;
for what direction does escape velocity apply? when we got explained it in class we had the "newtons cannon firing off a mountain" except this was parallel to the tangent of the earth at that point.
would the escape velocity apply if you fired the...
there is a formula for adding velocities
with 2 objects travelling at velocities v and w:
s = [v+w]/[1+(vw)/c^2] where like the relativity laws, the denominator is insignifcant at low velocites.
as v and w approach c the denominator will approach 2 and the numerator v+w will decrease...
