Displacement and Velocity
Hi all,
Say my finger location is x1 = 236 , y1 = 105 , x2 = 126, y2 =123 .
where
x1.y1 ==> current location and
x2,y2==> previous location
And i have distance computed using
dis = sqrt( (x2-x1)^2 - (y2-y1)^2 )
say angle is 60 degree .
Now, How far my finger move w.r.t its angle and what is its spead at given time 1sec ???? ?

Re: Displacement and Velocity
hi model,
I've made a diagram from what you have posted. see below.
It is NOT accurately to scale. But I have calculated the angles accurately using those co-ordinates.
No 60 degrees. Where does that come from?
And where does 1 sec come from? Is this the time taken to move from the previous location to the current location?
I'm not sure what you want help with.
