what is uncertainty principle which was given by werner heisenberg

Werner Heisenberg suggested that in case of small particles like electrons it is impossible to determine simultaneously both the position and velocity at a given instant with absolute certainty in the form of a well-known principle called Heisenberg’s uncertainty principle.This princilple is the consequence of dual nature of matter and radiation.It states that-
“It is impossible to measure simultaneously both the position and velocity(or momentum) of a microscopic particle with absolute accuracy or certainty.”
Mathematically it is given as-
Delta x * delta p is greater than and equal to h/4pi
or,
delta x * m delta v is greater than and equal to h/4pi
where,
delta x = uncertainty in position
delta p = uncertainty in momentum
h = Planck’s constant
m = mass of particle
delta v = uncertaintuy in velocity

According to Heisenberg’s uncertanity principle it is impossible to determine simultaneousle the momentum and position with exact precision.
we have
uncertanity in position(delta x)*uncertanity in momentum(delta p)=h/4pi
where h is the planck’s constant
In simple words suppose we have a ball of mass 200 gm,then the uncertanity in velocity is 25m/s.Then the uncertanity in position will be very less.It simply means that we can locate the position of the ball very easily.As uncertanity in position and velocity are inversely related
