If you measure a car momentum and position,you can measure them simultaneously, but wait a minute, you can use the camera to record velocity, thus momentum.
For measuring an atom, you disturb it when you measure it.
The limit of accuracy is del(p)del(x) > h(bar)/2.
Similar argument will apply to energy and time uncertainty.
which is del(e)del(t)>h(bar)/2

The statement is wrong. The uncertainty principle holds for macroscopic world also. But these uncertainties are so small that we can't appreciate it even with the best possible instruments that we have.

The uncertainty relation holds at ALL scales - from small to large. It is a fundamental principle.
However, it states [x,p] >= h/2pi (or equivalently for other conjugate variables). As h is of order 6 x 10^-34 Js its effects are entirely negligible for anything larger than the atomic scale. For instance, the mass of the proton is already 7 orders of magnitude larger.

Uncertainty principle is for microscopic body only becoz MASS of microscopic body is very small and hence, small change in position & velocity can be calculated.
In case of macroscopic body, mass is greater & hence small change in its position cant be calculated & thus uncertainty for position will not be applied there.

that's all about debris and waves. What Heisenberg did replaced into pick 2 houses position and momentum. position is a particle resources and momentum is unquestionably a wave resources thus. so as some thing won't be able to be a wave and a particle at the same time you may't degree position and momentum appropriately at the same time. truly the naughty issue replaced into to pick on momentum as a wave resources which motives a lot of bewilderment.

Uncertainity is true both philosophically and scintifically.
